Morphology

obturation = obturate (semi-transparent) = obturate + ation

The word is a predictable nominalization of 'obturate' with '-ation', but the firearms sense is specialized technical vocabulary.

Etymology

Obturation comes from the Latin verb obturare, which meant 'to stop up' and is like the English word obstruct ('to block'). In firearms, obturation is when the bullet or case expands to 'seal' the barrel so hot gas cannot escape, keeping the firing safe and efficient.
