How to say it
/diːn/
Valley, or 'dean' (administrative head)
/diːn/
Old English denu ('valley') as a place name and surname, or from the title 'dean' (Latin decanus, the senior member of a chapter). James Dean (1931-1955) is the indelible mid-century anchor.
Dean has two English roots that converged. The Old English denu ('valley') gave place names and the descriptive surname for someone living in a valley. The title dean (from Latin decanus, 'one set over ten,' the senior member of a chapter or college) gave a separate occupational surname. James Dean (Rebel Without a Cause, East of Eden, 1955) gave the name decisive mid-century anchor; his death at 24 froze the name in a particular kind of cultural amber. Dean Martin and Dean Acheson are the older anchors. As a first name Dean has been steady in the US top 300 since the 1950s. Single syllable, no shorter form.
