armless

the word 'armless' is a transparent english compound formed by combining the noun 'arm' with the adjectival suffix '-less'. the old english root 'earm' for arm is shared across germanic languages and is distantly related to the latin 'armus', referring to the shoulder joint. the suffix '-less', from old english '-lēas', originally conveyed a sense of being free from or devoid of something. the literal construction 'without arms' logically extended into a figurative, informal sense meaning harmless or incapable of causing damage, drawing a parallel between physical incapacity and a lack of threat.
