emotionless

the word "emotionless" is a modern english compound formed by combining the noun "emotion" with the adjectival suffix "-less". the core noun "emotion" entered english in the 16th century from middle french émotion, which itself derives from latin emovere, meaning "to move out, remove, or agitate". this latin root is composed of e- (a variant of ex-, meaning "out") and movere ("to move"), tracing back to the proto-indo-european root meue- ("to push away"). the suffix "-less" originates from old english -lēas, meaning "free from" or "devoid of", which is related to the verb lēosan ("to lose"). therefore, the literal construction "devoid of outward movement/agitation" evolved logically into the modern abstract meaning of "showing or feeling no emotion," conceptualizing emotion as an internal stirring that is absent.

Structure: emotion (feeling) + less (without) emotion: from latin emovere (to move out, agitate), via french émotion. in this compound, it functions as the base noun meaning "feeling". less: from old english -lēas (devoid of, free from), a suffix used to form adjectives meaning "without".
