distinctness

the word 'distinctness' is a relatively modern english formation, built upon the older adjective 'distinct'. 'distinct' entered english from latin distinctus, the past participle of distinguere, meaning 'to separate, mark off, distinguish'. this latin verb itself is composed of dis- (apart) and stinguere (to prick, quench), with an underlying sense of separating by making marks. the suffix '-ness' is a native english element from old english, used prolifically to convert adjectives into abstract nouns indicating a state or condition. therefore, 'distinctness' literally means 'the state or quality of being set apart or clearly different', a meaning that remains closely tied to its constituent parts.

Structure: distinct + ness distinct (from latin distinctus, meaning 'separated, distinguished', functioning as the core adjective) + ness (from old english -nes, a noun-forming suffix denoting a state or quality)
