What does acylate mean?
Acylation is one of the workhorse reactions of organic chemistry, and 'acylate' is its verb. To acylate a molecule is to attach to it an acyl group — a carbonyl carbon bonded to an alkyl or aryl substituent, written RCO–. Chemists typically achieve this by treating a substrate such as an alcohol, amine, or aromatic ring with an acylating agent like an acid chloride or acid anhydride, often in the presence of a catalyst. The products are esters, amides, ketones, and related compounds that underpin pharmaceuticals, polymers, and fragrances. The word derives from 'acyl', itself rooted in the Latin acetum, meaning vinegar, reflecting the historical connection between these reactions and acetic acid. Though almost exclusively encountered in laboratory and academic contexts, 'acylate' is precise, well-established terminology that any student of chemistry will meet early and use often.
To introduce an acyl group into a compound by chemical reaction.
"The chemists acylated the phenol to produce the ester."
Transitive; usually appears in passive constructions in experimental descriptions.
In chemistry, a salt formed by deprotonation of an oxonium ion or related cation.
"The acylate precipitated from the reaction mixture."
Applies only to the noun sense referring to salts.
"Several acylates were isolated during the study."
Every time chemists 'acylate' something, they're borrowing a fragment of vinegar's own family tree — the root traces back to acetum, Latin for vinegar.

Etymology of acylate
The verb 'acylate' is built on 'acyl', a term coined in the nineteenth century by German chemist Justus von Liebig from Greek roots meaning 'sharp' or 'vinegar-like', echoing the sour taste of acetic acid. It entered English scientific usage alongside the broader vocabulary of functional-group chemistry, following the pattern of verbs formed with the suffix '-ate' to denote the introduction of a group. Its closest relatives are other acyl-family terms such as 'acylation' and 'acetyl'.

How acylate is actually used
Strictly technical vocabulary confined to organic and bioorganic chemistry; not used in general conversation. The verb is standard in research literature and textbooks.
Easily confused with acylate
'Acyl' is the noun naming the RCO– group itself, while 'acylate' is the verb describing the act of attaching that group to a molecule.
