Morphology

invagination = invaginate (semi-transparent) = in + vagin + ation

Formed from the verb 'invaginate' with the noun-forming suffix '-ation', but the combining form 'vagin-' (meaning 'sheath') is not a standalone modern English morpheme, so the derivation is only partially obvious to learners.

Etymology

Invagination comes from the Latin parts in- meaning 'into' and vagina meaning 'sheath' or 'cover'. So the idea is 'folding into a sheath', which explains why invagination means tissue folding inward to form a pouch or pocket.
