Forms: 1800s– naphthyl, 1800s– naphtyl.

Origin: Formed within English, by derivation. Etymons: naphtha n., -yl suffix.

Etymology: < naphth- (in naphtha n.) + -yl suffix. With form naphtyl perhaps compare French naphtyl-, combining form, naphtyle, noun (1874).

Chemistry.

Either of two isomeric monovalent radicals, C₁₀H₇—, derived from naphthalene. Usually attributive or as a formative in chemical names.
