Word Nuance & Usage

As a verb, both 'fit' and 'fitted' are standard past-tense and past-participle forms; in American English, 'fit' is preferred for intransitive senses of matching in size ("the coat fit well"), while 'fitted' is standard globally for transitive senses of equipping, tailoring, or adjusting something ("they fitted the cabin with new shelves"). Note also that the noun sense meaning a sudden seizure or emotional outburst derives from a separate Old English root.

Word Origin & Etymology

The adjective, verb, and noun relating to suitability and size derive from Middle English fitten ('to array or marshal'), likely of Scandinavian origin akin to Old Norse fitja ('to knit together'). The noun sense meaning a sudden seizure or emotional outburst comes from an unrelated Old English root, fitt ('a struggle or conflict').
