Origin

Middle English: from Anglo-Norman French siwte, from a feminine past participle of a Romance verb based on Latin sequi ‘follow.’ Early senses included ‘attendance at a court’ and ‘legal process’; sense 1 of the noun and sense 2 of the noun derive from an earlier meaning ‘set of things to be used together.’ The verb sense ‘make appropriate’ dates from the late 16th century.
