Etymology
The word 'detritus' was adopted directly from Latin in the late 18th century, where 'detritus' meant "a wearing away." This Latin noun derives from the past participle of the verb 'deterere,' meaning "to wear away, to rub off." 'Deterere' itself is composed of the prefix 'de-' (down, away) and the root 'terere' (to rub, to wear). The semantic journey is vividly logical: from the literal action of rubbing away, to the resulting material that has been worn off or rubbed away. This core sense of discarded, worn-away material persists in its modern English meanings, encompassing both general debris and specific geological matter.
Analysis
The word is a simplex loanword from Latin. It cannot be meaningfully segmented into productive morphemes within modern English spelling.
