Keith (English)
Where does "Keith" come from?
The surname Keith likely originates from a Scottish placename in Moray, which roots back to the Proto-Brythonic word *koɨd, meaning 'wood.' This term stems from a Pictish word derived from the Proto-Indo-European *kayt-, reflecting a deep linguistic connection to forests and landscapes. A separate German branch of the surname emerged from the Middle High German word 'kit,' which translates to 'sprout' or 'offspring.'
