llan (Welsh)
Where does "llan" come from?
The Welsh word 'llan' traces its origins back to the Proto-Indo-European root *lendʰ-, which simply meant 'land' or 'heath.' Over centuries, it evolved through Proto-Celtic and Proto-Brythonic before firming up in Middle and Old Welsh as 'llann.' Eventually, the meaning shifted from a general plot of land to specifically denote an enclosure, often signifying a churchyard, monastery, or the parish settlement that grew around it.
