the word 'suited' originates from the verb 'suit', which entered english via old french 'suite', itself derived from vulgar latin 'sequita', a noun based on the latin verb 'sequi', meaning 'to follow'. the core concept of 'following' evolved through old french to mean 'to be agreeable or appropriate to', as something that 'follows' or matches the needs of a person or situation. the addition of the adjectival suffix '-ed', of old english origin, creates a participle that describes something as being made appropriate or, literally, clothed in a matching set of garments, extending the metaphor of compatibility.

Structure: suit (follow) + ed (adjective suffix) suit (from old french 'suite', meaning 'a following', from vulgar latin 'sequita', from latin 'sequi' meaning 'to follow'); ed (a suffix forming adjectives from nouns or verbs, from old english '-ede', '-ode', '-ad').
