Keith (English)
Where does "Keith" come from?
The English surname and given name Keith originates from a Scottish placename in Moray, which comes from Scottish Gaelic 'Cèith'[1]. This Gaelic form means 'wood' or 'from the battleground' and is probably borrowed from the Pictish form '*ᚉᚓᚈ', meaning 'wood' or a forest, which traces back to Proto-Brythonic '*koɨd'[1]. These Celtic terms ultimately descend from Proto-Indo-European roots referring to a forest or wasteland[3]. As a German surname, the word has a separate origin, coming from Middle High German 'kit', meaning 'sprout' or 'offspring'[1].
