unnoticed
UK: ʌnˈnəʊtɪst | US: ʌnˈnoʊtɪst
adj. not observed or perceived; escaping attention
The word "unnoticed" combines the Old English prefix "un-" (meaning "not") with the verb "notice" (derived from Latin "notitia," meaning "knowledge" or "observation"), and the suffix "-ed" to form an adjective. The prefix "un-" negates the root "notice," creating a term that describes something failing to attract attention. This logical construction reflects how English builds meaning through layered morphemes.
