1
person or thing used instead
A person or thing that is used instead of another person or thing.
Usage pattern:
a substitute for [something/someone]
Common mistake:
Learners sometimes confuse "substitute" (the thing used instead) with "replacement" as a verb. "Substitute" in this sense is a noun: you say "a substitute for sugar", not *"a sugar substitute for".
Synonyms
replacement (Very close in meaning; often slightly more formal and common in written English.)
|
stand-in (Informal; more often used for people, especially in work or performance situations.)
Antonyms
original (Refers to the first or usual person or thing, not the one used instead.)
Collocations
a good substitute
|a suitable substitute
|a direct substitute
|as a substitute for
|a sugar substitute
|a meat substitute

2
use one thing instead of another
To use one person or thing in place of another person or thing.
Usage pattern:
substitute [A] for [B]
Common mistake:
Many learners mix up the pattern with "replace". With "substitute" the most standard pattern is "substitute A for B" (use A instead of B). With "replace" you usually say "replace B with A" (put A instead of B). Some speakers do say "substitute B with A", but many style guides prefer "substitute A for B" for clarity.
Synonyms
replace (Very close in meaning; more common overall and slightly simpler, but the grammar pattern is different ("replace B with A" vs. "substitute A for B").)
Antonyms
keep (To continue using the same person or thing instead of changing it for another.)

3
player who comes on instead
A sports player who comes into the game to take another player's place.
Usage pattern:
a substitute for [a player]
Common mistake:
Learners sometimes confuse the noun "substitute" (the player) with the verb "to substitute" (the action of changing players). "The coach used a substitute" is about the person; "The coach substituted the player" is about the action.
Synonyms
reserve (Often used in sports for a player who is not in the starting team but may come on later; slightly more formal than "sub".)
Antonyms
starter (A player who begins the game on the field, not one who comes on later.)

4
replace one player with another
To remove one player from a game and put another player in instead.
Usage pattern:
substitute [player] for [player]
Common mistake:
Learners sometimes say *"substitute out" or *"substitute off" by copying other verbs. Instead, say "substitute [player]" or "substitute [player] for [player]", or use "take [player] off" in informal speech.
Synonyms
replace (Very similar meaning; in sports talk, "bring on" or "take off" are also common, but more informal and multi-word.)
Antonyms
keep on (To leave the same player in the game instead of changing them.)

5
teacher who replaces regular teacher
A teacher who works in a class when the normal teacher is not there.
Usage pattern:
a substitute in [class/grade]
Common mistake:
Learners sometimes think "substitute" here is always followed by "teacher". In many school contexts, especially in North America, people often just say "a substitute" and it is understood that this means a substitute teacher.
Synonyms
supply teacher (Common in British English for a teacher who replaces another for a short time; "substitute" is more common in North American English.)
Antonyms
regular teacher (The normal, permanent teacher for the class, not the temporary one.)
Collocations

6
serving as a replacement
Doing the job of another person or thing for a short time.
Usage pattern:
substitute [noun]
Common mistake:

Synonyms
temporary (Focuses more on the short time, while "substitute" focuses on taking the place of someone or something.)
Antonyms
permanent (Describes someone or something that is not just filling in or acting as a replacement.)
