Meaning & Origin
Whitsunday.
Whit is a boy's baby name of Old English origin, derived from Whitsunday or Whitney, with Whit meaning 'white' in Old English. It can also be seen as a given name form of Whitney, from the Old English hwīt (white) and ēg (island), meaning 'white island.'
Whit has a clean, preppy American quality — the kind of one-syllable name that sounds like it belongs on a lacrosse team or in a New England prep school, carrying a certain crisp Anglo-Saxon confidence.
