1
measure or express in numbers
To show or measure how much of something there is, usually with numbers.
用法模式：
to quantify [something]
常见错误：
Learners sometimes confuse "quantify" with "quantity" and say *"We need to quantity the data"* instead of "We need to quantify the data." Another mistake is using it without an object, as in *"We must quantify"* when they mean "We must quantify the problem."
近义词
measure (More general and slightly less formal; can involve tools or comparison, and is not always focused on giving a clear numeric value.)
反义词
describe (Focuses on explaining qualities in words rather than giving a numeric amount or exact figure.)

estimate size or importance
To say how big or important something is, even when it is hard to give a clear number.
用法模式：
to quantify [abstract_thing]
常见错误：
Learners may think "quantify" always means giving an exact number. In this sense, it often means estimating or judging size or importance, not necessarily producing a precise figure. They may also wrongly use an adjective like *"very quantify"* instead of using a phrase such as "hard to quantify."
近义词
assess (Focuses more on forming a judgment of value or size, and does not necessarily suggest using numbers or measurements.)
反义词
overlook (Means to fail to notice or consider something at all, instead of trying to estimate or judge its size or importance.)

apply a logical quantifier
In logic or math, to add words like "for all" or "there exists" to a variable or statement.
用法模式：
to quantify [variable/expression]
常见错误：
Learners may confuse this technical sense with the general meaning of simply "measuring" something. In logic and linguistics, it specifically refers to adding symbols or words like ∀ (for all) or ∃ (there exists) to a variable or expression.
近义词
bind (Technical term in logic and linguistics; refers to making a variable bound, often by quantifying it.)
反义词
free (In logic, a "free" variable is one that has not been quantified or bound in an expression.)
