Surface Forms

breech closer singular

Morphology

breech + closeable

The noun is compositionally built from 'breech' (the rear loading chamber) plus a clos-er/agent meaning 'one that closes'; thus its meaning 'a device that closes the breech' is directly derivable from the parts. Although the term is technical, the morphological formation (close → closer) and the noun-noun/agentive pattern are regular English, so a B1 learner who knows the constituents would readily infer the meaning.

Etymology

Breech closer: The noun breech closer names the metal block that closes the back of a gun. The phrase comes from the simple image: the metal piece fits into the gun's breech, the back of the barrel, to close it so the gun can be fired safely.
