Surface Forms

Morphology

chief + petty + officer

The components 'chief' (senior) and 'officer' (military rank) give learners a general idea that this is a senior naval rank, but 'petty' here is a non-literal, technical element (part of the fixed rank 'petty officer') and does not mean 'minor' in the phrase. Because the exact rank relationship and terminology are specific to military phraseology and cannot be fully derived from the ordinary meanings of the parts, the item is partially but not fully predictable to a B1 learner.

Etymology

Chief petty officer comes from putting chief (the leader) before petty and officer, where 'petty' used to mean 'small' or 'junior'. So a chief petty officer is the senior leader among the petty officers, which is why it means a senior noncommissioned officer in the navy.
