-olesuffix¹

Primary stress is usually located two syllables prior to this suffix; see e.g. arteriole n..

Origin: A borrowing from French. Etymon: French -ole.

Etymology: < French -ole (17th cent.) < classical Latin -olus (see -olus suffix), -ola (see -ola suffix¹), -olum (see -olum suffix).Most French words of this type with counterparts in English are borrowings of classical Latin words in -olus , -ola , -olum , but some appear to have been original formations in French, e.g. artériole arteriole n. (1673). The suffix originally occurred in technical words borrowed from French from the 18th cent. onwards, such as petiole n. During the 19th cent. words with the suffix began to be coined in English from nouns of classical Latin or ancient Greek origin, e.g. lobiole n. and bronchiole n. English formations are rare in the 20th cent.

Primary stress is retained by the usual stressed syllable of the preceding element.

Origin: A variant or alteration of another lexical item. Etymon: -ol suffix.

Etymology: Variant of -ol suffix, originally varying with it somewhat arbitrarily. After -ol suffix had developed the specific uses listed s.v., -ole came to be restricted to the uses indicated below.

Chemistry.

1. Unsystematically forming the names of compounds (as anisole, phenetole, safrole) which were regarded as being derived from carboxylic acids in the same way as ‘benzole’ (benzene) is from benzoic acid, i.e. by the loss of CO₂.Used chiefly in the 19th cent.

1852 Rep. Brit. Assoc. Advancem. Sci. 1851 i. 136 The use of the analogous termination ole for those [bodies] formed by the abstraction of 2 atoms of carbonic acid from the same [sc. vegetable acids] may be apt to cause some ambiguity. Thus we use the terms benzole, phenole, and anisole, as being derived respectively from the benzoic, salicylic, and anisic acids.

2. Forming the names of compounds containing five-membered, unsaturated rings with at least one hetero-atom, as carbazole, indazole, indole, pyrrole, thiazole, triazole.Although applicable in retrospect to older words like pyrrole (1835), this systematic use of -ole is of more recent date.

1928 Jrnl. Amer. Chem. Soc. 50 3078 For five-membered rings proposals made by Widman, Bouveault and others have found their way into use. The ending -ol or -ole appears in such names as pyrrole, imidazole and even dioxole (which is non-nitrogenous). It conflicts with the ending -ol for alcohols and phenols (hence the modified spelling -ole), but its use to denote a five-membered ring is well known.
