Morphology

obturator = obturate (transparent) = obturate + or

Formed by regular agentive suffixation of '-or' to the verb 'obturate', so its meaning 'a thing that stops up or closes an opening' follows directly from the base.

Etymology

The word obturator comes from the Latin verb obturare, meaning 'to stop up' or 'to close', and you can remember it like the everyday word obstruct, which also means 'to block'. So an obturator is a device that closes an opening, such as in the hard palate.
