Synonym discussion

Sense: adjective/1

Compliant, obedient, submissive, docile, and acquiescent all describe someone who follows the will of others, but with important differences. Compliant suggests a willingness to follow instructions or rules — it can be neutral or slightly negative when it implies a lack of independence ('compliant employees who never speak up'). Obedient is more active and positive, implying a conscious choice to follow authority out of respect or duty ('obedient children who listen to their parents'). Submissive carries a stronger negative tone, suggesting the person gives up power or self-respect ('a submissive partner in an unhealthy relationship'). Docile suggests a gentle, easy-to-manage temperament, often used for animals or children ('a docile horse that anyone can ride'). Acquiescent is the most formal and passive of the group, describing someone who agrees without enthusiasm ('an acquiescent board member who votes with the majority'). While compliant can describe both people and things (compliant with rules), the others refer almost exclusively to people or animals.

Etymology

LatinFrenchEnglish

Compliant comes from Latin 'complēre', meaning 'to fill up' or 'to complete'. In Vulgar Latin the meaning shifted to 'to fulfill a promise' or 'to satisfy'. The word entered Middle English through Old French 'complir', originally carrying the sense of 'to carry out, fulfill, or accomplish'. By the 17th century the meaning had broadened to include 'agreeing with someone's wishes or rules'. The modern sense of 'following requirements' reflects both the original idea of completion and the later social meaning of agreement.
