Common mistake:
Learners often confuse "infinite" (adjective) with "infinity" (noun). We say "an infinite number of stars" (adjective + noun) but "the infinity of space" (noun). Also, "infinity" is usually uncountable, so we normally do not say *"infinities"* in everyday language, even though it exists in advanced mathematical contexts.
Meaning
limitless extent or endlessness
Collocations
the infinity of space
|stretch into infinity
|seem like infinity
|to infinity
|into infinity
|an infinity of stars
Synonyms
endlessness (Focuses on having no end, especially in time, without emphasizing size or amount.)
|
limitlessness (Stresses the absence of any limits or boundaries, often in a more abstract way.)
Antonyms
finiteness (Highlights that something has fixed limits or an end, the opposite of being without limits.)
|
limit (A specific point or boundary where something stops, contrasting with having no boundary.)

Common mistake:
Learners may treat infinity as a normal number, saying things like *"divide by infinity to get zero"* as if infinity were a regular value, when in most mathematical systems it is a special concept, not an ordinary real number. They may also confuse "infinity" with "very big"; in math, infinity is not just a large number but something without any upper bound.
Meaning
mathematical unbounded value
Collocations
approach infinity
|tend to infinity
|goes to infinity
|plus infinity
|minus infinity
|countable infinity
Synonyms
unbounded value (Technical phrase that focuses on the idea of having no upper limit, common in mathematics and physics.)
|
divergent value (Used in specific mathematical contexts where a series or function does not settle on a limit and grows without bound.)
Antonyms
finite number (Any specific, limited number, which contrasts with the unbounded nature of infinity.)
|
bounded value (A value that stays within some fixed limits, opposite to a value that goes to infinity.)
Themes
