/ˈɛrəˌfɔr/

Forms: see aero- comb. form and -phore comb. form.

Origin: Formed within English, by compounding. Etymons: aero- comb. form, -phore comb. form.

Etymology: < aero- comb. form + -phore comb. form; in sense 2 probably after French aérophore (1866 in this sense; earlier as adjective in sense ‘which carries air (in insects or plants)’ (1798)).

1. Botany. In certain ferns: a specialized structure with numerous stomata for aeration, usually seen as a band of pale tissue on the stem or a small outgrowth at the base of a frond.

1933 Amer. Fern Jrnl. 23 76 Pinnae 25–30 pairs, alternate, sessile, furnished with a large, firm, elongate, brown aerophore at base below.

1993 Wildflower Spring 39/2 These are properly called aerophores and differ from the pneumatophores of the mangroves of coastal locations.

2. Any of several forms of respirator, esp. one with a portable supply of air for use by divers and miners. Now historical.
