infrequently
UK: /ɪnˈfriːkwəntli/ | US: /ɪnˈfriːkwəntli/
adv. not occurring often; rarely
The word "infrequently" combines the negative prefix "in-" (from Latin, meaning "not") with "frequent" (from Latin frequens, meaning "repeated or crowded") and the adverbial suffix "-ly" (from Old English -līce). The root "frequent" originally described dense or repeated occurrences, and the addition of "in-" logically reverses the meaning to "not often." The suffix "-ly" standardizes it as an adverb. This structure reflects a clear Latin-to-English adaptation, preserving the original morphemes' roles.
