A Simple Guide to Grammar Across Languages
Grammar often feels more complicated than it really is. One reason is that we use different labels for different levels of a sentence—but do not always explain how those levels fit together.
A noun is not the same thing as a subject.
A verb is not necessarily the whole predicate.
An adjective does not always appear directly before a noun.
And the subject of a sentence is not always the person deliberately performing an action.
The good news is that one simple distinction can make many grammar explanations much easier to understand.
When looking at a word or phrase, ask two separate questions:
What kind of element is it?
and:
What job is it doing in this sentence?
The first question is about parts of speech, also called word classes.
The second is about sentence roles or grammatical functions.
They are connected—but they are not the same.
The first level: what kind of word is it?
Words can be grouped according to how they behave in a language.
These groups are traditionally called parts of speech.
You probably already know many of them.
The two levels at a glance
Before looking at the details, it helps to see the two levels side by side.
Word classes: what kind of element is it?
These labels describe the grammatical type of a word.
- Noun: names a person, place, thing, event, or idea
Sarah, city, book, meeting, freedom - Verb: expresses an action, event, state, or relationship
run, call, happen, know, be - Adjective: describes a quality or characteristic
large, interesting, tired - Adverb: can express time, place, manner, frequency, or degree
yesterday, here, slowly, often, very - Pronoun: refers to someone or something without naming it again
I, she, it, they, someone - Determiner: helps identify, count, or specify a noun
a, the, this, my, some, three - Preposition: expresses a relationship such as place, time, direction, or accompaniment
in, after, to, with - Conjunction: connects words, phrases, or clauses
and, but, because, although
Sentence roles: what job does it perform here?
These labels describe how a word or phrase functions inside a particular sentence.
- Subject: the person, thing, or idea about which the sentence makes its central statement
Sarah called Daniel. - Predicate: what the sentence says about the subject
Sarah called Daniel. - Object: a person or thing closely affected or involved in the event expressed by the verb
Sarah called Daniel. - Complement: completes or identifies the meaning of the subject, object, or another part of the sentence
Daniel is a teacher.
Sarah seems tired. - Modifier: adds information about another word or phrase
the new student
the book on the table - Adverbial: gives information such as time, place, manner, reason, or purpose
Sarah called yesterday.
They met in Budapest.
The key difference is simple:
Word class tells us what kind of element something is. Sentence role tells us what it is doing in this sentence.
Nouns
Nouns typically name people, animals, places, objects, events, or ideas.
Sarah, teacher, dog, London, table, meeting, freedom
Verbs
Verbs typically express actions, events, states, or relationships.
run, call, happen, know, exist, be
Not every verb describes a visible action.
In:
Daniel knows the answer.
Knows is a verb, even though Daniel is not physically doing anything.
Adjectives
Adjectives describe qualities or characteristics.
tall, interesting, difficult, blue
They often appear before a noun:
an interesting book
But they can also appear after verbs such as be or seem:
The book is interesting.
Adverbs
Adverbs can express time, place, manner, frequency, degree, or the speaker’s attitude.
yesterday, here, slowly, often, very, probably
Examples:
Sarah arrived yesterday.
Daniel answered slowly.
The answer is probably correct.
Pronouns
Pronouns refer to people or things without naming them again.
I, you, she, he, it, we, they, someone
Instead of repeating:
Sarah called Daniel. Sarah spoke to Daniel.
we can say:
Sarah called Daniel. She spoke to him.
Determiners
Determiners help identify which thing we mean, how many there are, or whose they are.
a, the, this, those, my, every, some
Examples:
the book
my phone
those students
Prepositions
Prepositions express relationships involving place, time, direction, means, and many other ideas.
in, on, at, with, from, to, after
Examples:
in the room
after lunch
with Daniel
Conjunctions
Conjunctions connect words, phrases, or complete ideas.
and, but, or, because, although
Example:
Sarah stayed home because she was tired.
These categories describe what kind of grammatical element a word is.
But they do not yet tell us what the word is doing in a particular sentence.
The second level: what job does it perform?
Now consider this sentence:
Sarah called Daniel.
We can describe its words by type:
- Sarah is a proper noun;
- called is a verb;
- Daniel is a proper noun.
But we can also describe their roles:
- Sarah is the subject;
- called Daniel forms the main predicate;
- Daniel is the object.
These are sentence roles, not parts of speech.
Subject
The subject is the element around which the clause is grammatically organised.
It is often the person or thing performing an action:
Sarah opened the window.
But not always:
The window opened.
Daniel is tired.
Sarah heard a noise.
The window is not deliberately doing anything. Daniel is being described. Sarah experiences hearing rather than intentionally performing it.
They are still grammatical subjects.
For beginners, a useful definition is:
The subject is the person, thing, or idea about which the sentence makes its central statement.
This is not a perfect definition for every language, but it is more reliable than saying that the subject always “does the action”.
Predicate
The predicate tells us something about the subject.
Sarah called Daniel.
The window opened.
Daniel is tired.
Sarah became a doctor.
The predicate may express an action, event, state, quality, identity, or change.
Object
The object is closely connected to the verb and is often the person or thing affected by the event.
Sarah called Daniel.
Daniel opened the window.
They discussed the problem.
Modifier
A modifier adds information about another element.
the new student
Daniel’s old phone
the book on the table
Modifiers can be single words or larger phrases.
Adverbial
An adverbial gives information about circumstances such as time, place, manner, reason, or purpose.
Sarah called yesterday.
They met in Budapest.
Daniel answered carefully.
We stayed home because it was raining.
An important detail is that an adverbial does not have to be an adverb.
Compare:
Sarah called yesterday.
Sarah called after lunch.
Sarah called last week.
These expressions have different grammatical forms:
- yesterday is an adverb;
- after lunch is a prepositional phrase;
- last week is a noun phrase.
But all three perform a similar sentence role: they tell us when Sarah called.
The same kind of word can perform different jobs
Look at the name Daniel:
Daniel called Sarah.
Sarah called Daniel.
Sarah spoke to Daniel.
This is Daniel’s book.
Daniel is a proper noun in every sentence.
But its role changes:
- subject;
- object;
- part of a prepositional phrase;
- possessor.
This is the central idea:
Part of speech tells us what kind of element something is. Sentence role tells us what it is doing here.
The same principle applies to adjectives.
the tired student
The student is tired.
Tired is an adjective in both sentences.
In the first, it modifies the noun student.
In the second, it helps form the statement made about the student.
The word type stays the same, but its place in the sentence structure changes.
Sometimes even the word type can change
The distinction becomes slightly more interesting in English because the same written form can sometimes belong to different word classes.
Consider call:
I received a call.
Please call me.
In the first sentence, call is a noun.
In the second, it is a verb.
Or email:
I sent an email.
Please email the document.
Or clean:
a clean room
Please clean the room.
English often allows words to change category without adding a visible ending.
This means that even the question “What part of speech is this word?” sometimes needs more context.
A better question is:
How is this word being used in this sentence?
How do we know who is doing what?
Once we understand the difference between word type and sentence role, another question appears:
How does a language show which participant is the subject, object, recipient, or other part of the event?
Languages have several tools available:
- word order;
- endings attached to words;
- prepositions or postpositions;
- particles;
- changes in the verb;
- pronoun forms;
- special sentence constructions;
- meaning and context.
Most languages use several of these signals at the same time.
But they do not divide the work in the same way.
English: position is especially important
English normally uses the order:
Subject – Verb – Object
Compare:
Sarah called Daniel.
Daniel called Sarah.
The names do not change form. Their position tells us who called whom.
English is not based on word order alone, however.
Pronouns also provide clues:
She called him.
He called her.
And sentences can be reorganised:
Sarah encouraged Daniel.
Daniel was encouraged by Sarah.
In the second sentence, Daniel becomes the grammatical subject, although he is still the person receiving the encouragement.
Word order is essential in English, but it works together with pronouns, auxiliary verbs, prepositions, and sentence structure.
French and Spanish: familiar patterns with important differences
French and Spanish commonly use the same basic SVO order as English.
French:
Sarah appelle Daniel.
Spanish:
Sara llamó a Daniel.
But both languages add other signals.
In French, object pronouns usually appear before the verb:
Sarah **l’**appelle.
“Sarah is calling him.”
In Spanish, the verb ending often provides information about the subject:
Llamé a Daniel.
“I called Daniel.”
The Spanish sentence does not need a separate word for I, because the verb form already gives that information.
Spanish also commonly places a before a specific human object:
Sara llamó a Daniel.
So even closely related European languages do not organise the same information in exactly the same way.
German: both word order and case matter
German provides a useful bridge between English and languages with richer case systems.
Compare the articles:
der Mann
den Mann
The form of the article can help show whether the noun phrase is functioning as a subject or object.
German also has strict rules about where verbs appear, especially in main and subordinate clauses.
This means that German learners must pay attention both to:
- the position of sentence elements;
- changes in articles, pronouns, and sometimes nouns or adjectives.
German does not rely as heavily on position as English, but word order is still far from random.
Hungarian and Russian: endings carry more information
Hungarian and Russian use case marking more extensively than English.
In Hungarian, the direct object is commonly marked with -t:
Sarah felhívta Danielt.
“Sarah called Daniel.”
Because the ending marks Daniel as the object, the phrase can move to another position without becoming the subject.
But the new order may change the emphasis.
A sentence can highlight:
- who performed the action;
- whom it affected;
- what information is new;
- what is being contrasted.
Russian also changes noun, pronoun, and adjective forms according to case.
This allows more word-order variation than English, but Russian word order still communicates focus and information structure.
It is therefore better to say that Hungarian and Russian have more flexible word order—not completely free word order.
The endings identify many grammatical relationships, while the order often helps shape the message.
Mandarin Chinese: fewer endings, more work for order and context
Mandarin Chinese has relatively little inflection.
Verbs do not normally change according to the person of the subject, and nouns do not use a case system like Russian or Hungarian.
The common basic order is SVO:
subject – verb – object
As a result, position is an important clue.
But Mandarin is not simply a line of fixed, unchanging words.
It also uses:
- particles;
- aspect markers;
- topic structures;
- classifiers;
- special constructions;
- context.
A sentence may begin with a topic that is not identical to the grammatical subject. Certain constructions can also place an object before the main verb.
Mandarin shows that a language can have little word inflection while still possessing a rich and highly organised grammar.
Japanese and Korean: small markers after noun phrases
Japanese and Korean commonly place the verb near the end of the sentence.
Their typical order is:
Subject – Object – Verb
Both languages use small elements after noun phrases to help identify their roles.
In Japanese, for example:
- -ga commonly marks a subject-related phrase;
- -o commonly marks a direct object;
- -wa often marks the topic or a contrast.
A simplified example is:
Sara-ga Daniel-o hometa.
“Sarah praised Daniel.”
The markers help show which name has which role.
Korean has similar subject, object, and topic markers.
However, these markers can sometimes be omitted in casual speech when the intended meaning is clear. Listeners then rely more heavily on context, word order, and shared knowledge.
The topic is also not always the same as the subject—an important idea in both languages.
Arabic: one language name, several grammatical realities
Arabic needs a little caution because formal written Arabic and everyday spoken varieties are not identical.
Formal Arabic can use:
- word order;
- agreement on the verb;
- pronoun forms;
- prepositions;
- case endings in especially careful or fully marked language.
Both verb–subject–object and subject–verb–object patterns are possible.
In ordinary writing, short vowel marks—and therefore many visible case distinctions—are usually omitted.
In everyday spoken Arabic varieties, the old case-ending system is also much less prominent or largely absent.
So Arabic does not have one simple answer to the question “How does it mark the subject and object?” The answer depends partly on which form of Arabic we mean.
Hindi: markers after nouns
Hindi usually places the verb at the end and often uses elements after nouns, called postpositions.
English says:
with Daniel
Hindi follows the general pattern:
Daniel with
Certain markers can also identify recipients, specific objects, or the agent-like participant in particular past constructions.
But these markers are not attached mechanically in every sentence. Their use depends on factors such as:
- whether the participant is human;
- whether it is specific or already known;
- the type of verb;
- whether the event is viewed as completed.
Hindi is a good reminder that grammatical roles are not always marked in exactly the same way in every tense and construction.
Languages distribute the work differently
It is tempting to divide languages into simple pairs:
- word-order languages versus case languages;
- rigid languages versus free languages;
- simple languages versus complicated languages.
Reality is more interesting.
English places a great deal of responsibility on position.
Hungarian and Russian place more information on noun forms.
Spanish shares the work between word order, verb endings, pronouns, and object marking.
German uses both word order and case.
Mandarin relies on position, constructions, particles, and context.
Japanese and Korean often place grammatical markers after nouns.
Arabic combines different tools depending on the variety and context.
No language uses only one signal.
They solve similar communication problems by distributing information differently.
What should a language learner pay attention to?
When reading or listening to a new language, do not look only for individual vocabulary words.
Ask a few structural questions.
What kind of element is this?
Is it a noun, verb, adjective, pronoun, preposition, or another type of word?
What role does it perform here?
Is it the subject, object, description, modifier, recipient, or information about time and place?
What signals that role?
Look for:
- position;
- endings;
- articles;
- pronoun forms;
- particles;
- prepositions or postpositions;
- changes in the verb;
- the surrounding context.
Is the sentence neutral or emphasising something?
A different order may not change who did what, but it may change what the speaker wants to highlight.
This is especially important in languages with flexible word order.
The central idea
Grammar becomes much easier when we separate two questions:
What kind of word or phrase is this?
and:
What is it doing in this sentence?
A noun is not automatically a subject.
A subject is not always a deliberate doer.
An adjective does not only appear before nouns.
The same sentence role can be expressed by different kinds of phrases.
And languages do not all use the same signals to show who did what to whom.
Once we start seeing grammar as a system of types, roles, and signals, it becomes less like a long list of arbitrary rules.
The languages are different—but the questions they need to answer are surprisingly similar.

This article provides a practical map of the main ideas. The full distinctions are more nuanced, especially when we compare languages with very different grammatical systems.
