'articleless' originates from Modern English, specifically the combination of the noun 'article' and the suffix '-less', where 'article' came (via Old French 'article') from Latin 'articulus' meaning 'small joint/part' and in grammar 'article' referred to a grammatical marker, and '-less' (from Old English 'lēas') meant 'without'.

'article' came into English via Old French 'article' from Latin 'articulus', and the productive English suffix '-less' (Old English 'lēas') combined with 'article' in later Modern English formations to create adjectives such as 'articleless'.

Initially formed to mean 'lacking an article' (i.e., 'without an article'), and the meaning has remained essentially the same in modern usage.
