approximate calculation of size or cost
A careful guess about how big, how many, how long, or how much something will cost or be worth.
Tipar de utilizare:
an estimation of [amount/cost/size]
Greșeală frecventă:
Learners sometimes confuse "estimation" with the verb "estimate". Use "estimation" as a noun ("make an estimation"), and "estimate" as a verb ("to estimate the cost"). Also, avoid saying *"do an estimation"*; "make" or "give" is more natural.
Sinonime
estimate (More common and slightly less formal; can be both noun and verb.)
|
approximation (Stresses that the value is not exact, often a bit more technical.)
Antonime
exact calculation (Highlights that something is worked out precisely, not approximately.)
|

personal judgment or opinion
What someone thinks or believes about how good, important, or right something or someone is.
Tipar de utilizare:
in [someone]'s estimation, [clause]
Greșeală frecventă:

Sinonime
opinion (More general and common; does not suggest the careful weighing that "estimation" can imply.)
|
assessment (Suggests a more thorough or systematic judgment than "estimation".)
Antonime
fact (Contrasts a personal judgment with something that is objectively true.)
|
certainty (Opposes the idea of a tentative or personal judgment.)

level of respect or regard
How much people respect or value someone or something.
Tipar de utilizare:
hold [someone/something] in [high/low] estimation
Greșeală frecventă:

Sinonime
esteem (Very close in meaning; used more often in formal or written English.)
|
regard (Slightly broader; may be less intense than "esteem" or "high estimation".)
Antonime
disrespect (Shows a clear lack of respect, the opposite of high estimation.)
|
contempt (A strong negative attitude, much lower than low estimation.)

statistical or mathematical estimating process
In math, science, or engineering, the way to find an estimated value for something you do not know, using numbers or data.
Tipar de utilizare:
estimation of [parameter/value] using [method]
Greșeală frecventă:
Learners may not realize that in technical texts "estimation" often refers to a formal method, not just a quick guess. In these contexts, it usually goes with words like "parameter", "model", or a named method such as "maximum likelihood".
Sinonime
estimation procedure (More explicit in technical writing; highlights the method used.)
|
inference (In statistics, can overlap when talking about drawing conclusions from data, but is broader than estimation alone.)
Antonime
measurement (In technical fields, measurement finds an observed value directly, rather than inferring or estimating it.)
|
exact computation (Indicates that no approximation is involved, unlike in estimation.)
