The word 'suiter' is built upon the core concept of "following" or "pursuing", inherited from the Latin verb 'sequi'. This root gave rise to a family of English words related to sequence, consequence, and pursuit. In the legal and romantic spheres, a 'suit' historically referred to the act of following up a claim or courting a person. By adding the agent suffix '-er', the noun 'suiter' was formed to specifically denote the person who initiates such a pursuit, whether in a court of law, a business negotiation, or matters of the heart. Thus, the modern meanings all logically stem from the original sense of one who actively follows a course of action to achieve an objective.

Structure: suit (to follow, to pursue) + er (agent suffix) - suit: From Anglo-French 'siute', Old French 'suite', meaning "act of following, pursuit". Ultimately from Latin 'sequi', meaning "to follow". - er: A Germanic agent noun suffix, used to form nouns denoting a person or thing that performs the action of the verb.
