What does derivate mean?
"Derivate" is a noun denoting something that has been derived from another source — a form, product, or version originating in a parent entity. It is closely related to, and often interchangeable with, its far more common sibling "derivative," but it survives today mainly within technical and scientific language. In chemistry, for example, a derivate is a compound produced by modifying a parent substance, as when chemists test various derivates of a known molecule for improved properties. Outside such specialized settings, most writers prefer "derivative," which carries additional senses in finance and mathematics. "Derivate" traces back through Latin derivare, meaning to draw off or derive, sharing that root with "derive" and "derivation." Because of its rarity, using "derivate" signals a deliberately technical tone; in ordinary prose, "derivative" is almost always the safer choice. The word's persistence in laboratory literature makes it a small but genuine marker of scientific register.
nounSomething derived from another source or thing, especially in technical or scientific contexts; in chemistry, a compound formed from a parent substance by chemical modification.
- Something obtained or developed from another thing; a product of derivation, especially in technical or scientific contexts.
- A chemical compound produced from a parent compound by substitution or other modification.
"The new drug is a derivate of an older compound first synthesized in the 1950s."
"Each derivate of the base polymer has distinct thermal properties."
"The researchers tested several derivates of the original molecule for antibacterial activity."
The plural follows the regular English pattern; it appears mainly in scientific texts.
"The team compared the biological activity of several derivates of the lead compound."
Chemists still write "derivate" where everyone else says "derivative" — one of the few places this centuries-old word survives.

Etymology of derivate
"Derivate" comes from Latin derivatus, the past participle of derivare, meaning "to draw off" or "to derive" — literally to divert water from a stream. English borrowed the word in the early modern period alongside "derive" and "derivation." Its Latin root de- (down, away) combined with rivus (stream) also underlies related words such as "river." Over time, "derivative" displaced "derivate" in general English, leaving the latter chiefly in scientific usage.
How derivate is actually used
"Derivate" is formal and largely restricted to scientific registers, particularly chemistry; "derivative" is far more common in general usage and is preferred outside technical contexts.
Easily confused with derivate
"Derivative" is the standard everyday word for anything derived from a source (and also a financial instrument or calculus concept), while "derivate" is rarer and largely confined to technical writing such as chemistry.
