detriment

The word "detriment" entered English in the late Middle English period, borrowed directly from the Latin detrimentum, meaning 'loss, damage, a rubbing away'. This Latin noun derives from the verb deterere, 'to wear away, rub off', which is itself composed of de- 'away' and terere 'to rub'. The core semantic logic, from its Proto-Indo-European root terh₁- ('to rub, turn, drill'), connects the physical act of grinding something down to the abstract concept of causing gradual harm or loss. Thus, the modern meaning evolved from a literal sense of wearing away to a figurative one, denoting anything that causes damage or the state of being impaired.

The word "detriment" is a simplex loanword from Latin. It cannot be meaningfully segmented into productive morphemes in modern English spelling without resorting to reconstructed Latin forms (e.g., deterere 'to wear away').
