1
very unpleasant or annoying
Very unpleasant or very annoying, used in an informal way.
Usage pattern:
a beastly [noun]
Common mistake:
Learners sometimes think "beastly" can be used in very formal writing, but this sense is informal and often sounds a bit British or old-fashioned. In American English, words like "awful" or "terrible" are more common in this meaning.
Synonyms
awful (Very common and neutral; slightly less old-fashioned than "beastly".)
|
horrible (Often stronger and more emotional; not as British-sounding as "beastly".)
|
nasty (Suggests something unpleasant in a dirty or mean way.)
Antonyms
pleasant (Describes something enjoyable or nice, the opposite of unpleasant.)
|
nice (Simple, positive word often used where "beastly" would be negative.)

3
cruel, harsh, or brutal
Very cruel or very unkind, as if the person does not care about others' feelings.
Usage pattern:
[someone] is beastly to [someone]
Common mistake:
Learners sometimes think this meaning is only about animals because of the word "beast", but here it usually describes human behavior that is very unkind or cruel. Also, "beastly" is not as strong as legal terms like "inhuman" or "barbaric" in serious reports.
Synonyms
cruel (Direct and common; focuses on causing pain or suffering.)
|
brutal (Stronger, often suggesting physical violence or extreme harshness.)
|
mean (Everyday word for unkind; usually sounds less strong than "beastly".)
Antonyms
kind (Shows care and concern for others, the opposite of cruel behavior.)
|
gentle (Soft and careful in treatment, opposite of harsh or brutal.)

like a beast or animal
Like an animal in body or mind, especially when talking about strong desires or low, wild behavior.
Usage pattern:
beastly [noun]
Common mistake:

Synonyms
bestial (More formal and technical; often used in serious or religious contexts.)
|
animalistic (Focuses on raw, instinctive animal qualities.)
Antonyms
humane (Emphasizes human kindness and moral feeling, contrasted with animal-like lack of restraint.)
|
civilized (Suggests controlled, socially developed behavior instead of primitive, animal-like behavior.)
