Morphology

capillary = capill + ary

The term is built from the Latin combining form 'capill-' plus '-ary', but because 'capill-' is not an English word, learners cannot reliably infer the specialised meaning 'very thin tube' from known morphemes.

Etymology

Capillary comes from the Latin root capill- meaning 'hair', so a capillary tube is named for being as thin as a hair. Because it is so narrow, a capillary can draw up or move small amounts of liquid, which is why scientists use them.
