The word 'untranslated' is a modern English formation built upon the established verb 'translate'. Its core logic originates from Latin: 'trans-' (across) combined with 'latus', the past participle of 'ferre' (to carry), literally meaning "carried across." This metaphor of carrying meaning across a linguistic barrier gave rise to the concept of translation. The Germanic negative prefix 'un-' is then attached to this compound, creating a straightforward adjective that means "not carried across," or more precisely, not converted from one language to another. Thus, the word's construction transparently reflects its meaning through the assembly of these historical morphemes.

Structure: un (not) + trans (across) + lated (carried) - un: A prefix of Germanic origin (Old English 'un-'), meaning "not," used to form negatives. - trans: A Latin prefix (from Latin 'trans-'), meaning "across, beyond, through." - lated: Derived from the past participle stem of the Latin verb 'ferre' (to carry, bear), which, via Old French, gave rise to the English verb 'translate' (to carry across). The '-lated' here is a direct substring from the past participle form 'translated'.
