'badgeless' originates from English, specifically formed from the noun 'badge' and the suffix '-less', where '-less' meant 'without'.

'badge' appears in Middle English (from Anglo-Norman/Old French roots) and the suffix '-less' comes from Old English 'lēas' meaning 'without'; these elements combined in Modern English to produce the compound 'badgeless'.

Initially, the components conveyed 'without a badge', and over time the compound has retained this straightforward meaning of 'lacking a badge'.
