What does differentiate mean?
To differentiate is to perceive, express, or establish a difference — whether between things, people, ideas, or qualities. The verb has two principal uses: intransitively, it means to recognize distinctions, as when a doctor learns to differentiate between similar symptoms; transitively, it means to make something distinct, as when a brand differentiates its product from competitors'. In mathematics, differentiate has a specialized sense: to compute the derivative of a function, revealing its rate of change at any given point. The word is moderately formal, appearing often in academic, scientific, commercial, and educational contexts, though it is perfectly natural in general writing. Its Latin roots — differre, meaning to carry apart or differ — connect it to a family of related terms such as difference and differential. Precision is central to the word's character: to differentiate well is to see clearly what sets one thing apart from another.
To recognize or show how two or more things are different from each other.
"Children learn to differentiate living things from non-living ones at an early age."
Often used with "between" (differentiate between X and Y) or with a direct object and "from" (differentiate X from Y).
To make something or someone distinct or set apart from others.
"The restaurant differentiates itself through its commitment to locally sourced ingredients."
Commonly used reflexively as "differentiate oneself" in business and marketing contexts.
(Mathematics) To obtain the derivative of a function.
"Differentiate both sides of the equation with respect to x."
The same Latin root that gives us "different" also powers "differentiate" — and in mathematics, it's what you do when you find a derivative, literally extracting a rate of change from a function.

Etymology of differentiate
"Differentiate" derives from Medieval Latin differentiatus, the past participle of differentiare, meaning "to distinguish," itself built on differentia — "a difference" — from the Latin verb differre, "to carry apart, to differ." The word entered English in the early 19th century, first appearing in scientific and philosophical writing before broadening into everyday use alongside its mathematical sense. It shares this Latin ancestry with cognates including difference, different, differential, and indifferent.

How differentiate is actually used
"Differentiate" is somewhat formal and common in academic, scientific, business, and technical writing. In everyday speech, people often prefer simpler phrasings like "tell apart" or "see the difference." It is frequently followed by "between" plus the items compared, or by a direct object plus "from."
Easily confused with differentiate
"Different" is an adjective meaning not alike, while "differentiate" is a verb describing the act of recognizing or creating that difference.
"Discriminate" can mean distinguishing carefully (like differentiate) but also carries a strong sense of unfair treatment based on prejudice, which differentiate does not have.
