almost but not completely exact
Almost correct, but not exactly right in number, size, time, or shape.
Padrão de uso:
an approximate [number/amount/time/position]
Erro comum:
Learners often confuse the adjective "approximate" with the adverb "approximately". Use "approximate" before a noun (e.g., "an approximate price"), and "approximately" before a number or after a verb (e.g., "It costs approximately $50"). Many learners also overuse "about" and "around" in formal writing where "approximate" or "approximately" would sound more natural.
Sinónimos
rough (More informal; often suggests a quick guess without much detail.)
|
estimated (Highlights that a calculation or guess has been made; slightly more formal.)
Antónimos
exact (Stresses that there is no difference at all between the value and reality.)
|
precise (Emphasizes a very high level of accuracy and detail.)

to estimate roughly or closely
To give a number or amount that is almost right, but not exact.
Padrão de uso:
to approximate [a number/amount/value]
Erro comum:
Learners sometimes say *"make an approximate"* as a verb. Instead, use "approximate" as the verb (e.g., "We approximated the cost"), or use the noun "an approximation" ("We made an approximation"). Another mistake is using "approximate" without an object in this sense; for estimating, it normally takes a direct object such as "the cost" or "the number".
Sinónimos
estimate (Most common everyday word; can be based on guesswork or calculation.)
|
calculate (Suggests using numbers or a method, and may imply more precision than "approximate".)
Antónimos
determine (Implies finding the exact or fully correct value, not just a near one.)
|
pinpoint (Stresses finding an exact position or amount, not an approximate one.)
Colocações

to be nearly the same as
To be almost the same as something else in level, quality, or shape.
Padrão de uso:
to approximate [something] / to approximate to [something]
Erro comum:
Learners may confuse this "be similar" sense with the "estimate" sense and use the wrong structure. For similarity, "approximate" is often followed by "to" or a direct object meaning the thing it is similar to (e.g., "The model approximates reality" or "The design approximates to a circle"). Using it with numbers to mean "guess" (e.g., *"The design approximates the cost"*) is incorrect.
Sinónimos
resemble (Focuses on being similar in appearance or general character.)
|
approach (Often used for levels or standards being nearly reached.)
Antónimos
differ from (Emphasizes being not the same as something in a noticeable way.)
|
contrast with (Highlights clear and often strong differences rather than similarity.)
