anchoicadj.

Brit.

/aŋˈkəʊɪk/, U.S.

/ænˈkoʊɪk/

Origin: A borrowing from Greek, combined with an English element. Etymons: Greek ἄγχειν , -ic suffix, -oic comb. form.

Etymology: < ancient Greek ἄγχειν to squeeze, strangle ( < the same Indo-European base as classical Latin angere to choke, strangle: see angor n.) + either -oic comb. form or -ic suffix; so called on account of the suffocating effect of its gaseous products when heated. The -o- may reflect either -oic comb. form or (irregularly) ἄγχω , first person singular present indicative of the Greek verb (compare quot. 1858).

Chemistry. Now rare.

anchoic acid n. a dicarboxylic acid found in wheat, barley and rye, used as a reagent in chemical synthesis and as a component of creams and gels used to treat acne; = azelaic acid at azelaic adj.Systematic name: nonanedioic acid; HOOC(CH₂)₇COOH.Now chiefly in lists of alternative names for the chemical.
