the word 'unmodified' is a modern english formation built upon the past participle 'modified'. the core root 'modif-' originates from the latin verb 'modificare', meaning "to measure, to limit, or to alter", which itself stems from 'modus' (measure, manner) and 'facere' (to make). the prefix 'un-', of germanic origin, is a prolific negator in english. thus, the literal construction "not + having been changed" directly and logically yields the contemporary meaning of something remaining in its original state without alteration.

Structure: un (not) + modif (to change) + ied (adjective suffix) - un: a prefix of english origin (from old english), meaning "not". - modif: a root derived from latin 'modificare', meaning "to measure, to limit, to change". - ied: a suffix of english origin, forming past participles and adjectives, from old english '-od', '-ad'.
