Occasionally, hairs, scales, or bristles may also be present on the receptacle.

词源

From Middle English receptacle, from Anglo-Norman receptacle and Middle French receptacle (“organ containing a fluid; gathering place; water basin”) (modern French réceptacle), from Latin receptāculum (“animal enclosure, container, place of refuge, receptacle, repository, reservoir, shelter”), from receptāre (“to harbour, to receive, to shelter”) or receptō (“to receive back or again, to recover”), frequentative of recipiō (“to receive; to hold back, to reserve”) (from re- (“back, again”) + capiō (“to hold”)) + -culum (suffix forming nouns from verbs, particularly nouns representing tools and instruments); cognate with Italian recettaculo, ricettaculo, Portuguese receptáculo, Spanish receptáculo.
