cannula
Cannula (noun) means a thin tube put into the body to remove or add fluid, such as during medical treatment.
Etymology
The word was borrowed from Late Latin cannula, canula, meaning "tubular surgical instrument", which itself came from Latin cannula ("reed; small reed- or tube-shaped object"). This was built from canna ("cane; reed; object made from or shaped like a cane or reed") plus -ula, the feminine form of the diminutive suffix -ulus. Canna traces back to Ancient Greek κᾰ́ννᾰ (kắnnă, "reed"), from Akkadian qanûm ("cane; reed"). The plural cannulae is likewise borrowed from Late Latin cannulae.
