单词 pipette
释义

pipetten.

Brit. /pᵻˈpɛt/, U.S. /paɪˈpɛt/
Forms: late Middle English pypet, 1800s– pipette, 1900s– pipet (U.S.).
Origin: A borrowing from French. Etymon: French pipette.
Etymology: Originally < Middle French pipette little flute (1462; earlier in Old French as pipet (first half of the 13th cent.)) < pipe (see pipe n.1) + -ette -ette suffix. In sense 2 reborrowed < French pipette ( L. J. Thénard Traité de chim. élém.(1816) IV. Descr. des ustensiles 59).Earlier currency of the word is perhaps implied by the surname Rico. Pypet (1332), although (if this word at all) it is unclear whether this should be interpreted as reflecting the Middle English or an (otherwise unattested) Anglo-Norman parallel.
