Verb
B2
event
1
happen at the same time
To happen at the same time as something else.
Usage pattern:
to coincide with [event/time]
Common mistake:
Learners often forget the preposition and say *"coincide the party"* instead of *"coincide with the party"*. Another common mistake is using *"coincide together"*, which is redundant; *"coincide"* already means happening at the same time. Also, do not confuse the verb *"coincide"* with the noun *"coincidence"*.
Synonyms
concur (More formal; often used in written or official contexts for events happening together.)
|
overlap (Suggests that periods of time cover some of the same span, not always exactly the same start and end.)
Antonyms
clash (Used when times or events are in conflict so you cannot attend both.)
Collocations

|exactly coincide
|roughly coincide
|dates coincide

2
be in full agreement
To be the same as, or very close to, another idea, opinion, or result.
Usage pattern:
to coincide with [view/result/fact]
Common mistake:
Learners sometimes use *"coincide"* only for time and forget it can mean *"be the same as"* for ideas or results. They may also say *"coincide to"* instead of the correct *"coincide with"*.
Synonyms
agree (More common and less formal; often used for people, while *"coincide"* is frequent for views, facts, or results.)
|
match (Less formal; suggests being the same or very similar, especially in details or numbers.)
|
align (Often used for policies, interests, or strategies becoming similar or supportive of each other.)
Antonyms
contradict (Used when one statement, result, or opinion is opposite to or cannot be true at the same time as another.)

occupy the same position in space
To be in the same place in space as something else, so they lie on each other.
Usage pattern:
to coincide with [line/point/position]
Common mistake:
Learners sometimes confuse *"coincide"* with *"collide"*. *"Coincide"* means to share the same position, especially in math or diagrams, while *"collide"* means to hit or crash into something.
Synonyms
overlap (Can describe shapes or areas covering the same region, though not always perfectly.)
|
superimpose (Usually describes intentionally placing one shape directly over another so their parts match.)
Antonyms
diverge (Used especially for lines or paths that move apart instead of lying on top of each other.)
