-less (English)

Where does "-less" come from?

The English suffix '-less' descends through Middle English '-les'[1] from the Old English adjective-forming suffix '-lēas'[1], which denotes a lack of something. This ancestral element traces back to Proto-West Germanic '*-laus'[1] and Proto-Germanic '*-lausaz'[1], meaning 'loose'[1], which itself derives from an adjectival formation of '*leusaną', meaning 'to lose'[2]. Throughout its long history, the suffix has maintained its core function of signifying absence and shares roots with numerous Germanic cognates such as Dutch '-loos', German '-los', and Swedish '-lös'[1].
