词源

Borrowed from Late Latin cannula, canula (“tubular surgical instrument”), from Latin cannula (“reed; small reed- or tube-shaped object”), from canna (“cane; reed; object made from or shaped like a cane or reed”) + -ula (feminine form of -ulus (diminutive suffix). Canna is derived from Ancient Greek κᾰ́ννᾰ (kắnnă, “reed”), from Akkadian 𒂵𒉡𒌑𒌝 (qanûm, “cane; reed”).
The plural form cannulae is borrowed from Late Latin cannulae.
