Pronunciation
Forms
importūnus (feminine importūna, neuter importūnum, comparative importūnior, superlative importūnissimus); first/second-declension adjective[1] Also spelled inportūnus.[2]
Etymology
The OLD takes it as formed as the opposite of opportūnus “convenient”, originally a nautical metaphor, from in- “not” and portus “harbour”.[2][3][1] Wiktionary traces ⟨portus⟩ to Proto-Indo-European *pértus (“crossing”).[1]
Earliest recorded meaning
Köbler's earliest source is Livius Andronicus, whom he dates 280/260–before 200 BC.[4]
Semantic evolution
It meant unsuitable, unfavourable, inconvenient, as in Cicero, and of a place hard to approach, as in Sallust; of persons regardless of others, troublesome, oppressive, as in Plautus; and perverse, as in Pliny.[2][5]
In Ecclesiastical Latin it meant unsuitable, troublesome, rude.[6] British Medieval Latin used it for unseasonable, of times and weather.[7] Medieval Latin importūnārī “to be troublesome” is behind English importune (1520s).[8]
