Welsh word meaning 'mansion' or 'palace,' used as a place-based given name.
Plas is a Welsh word meaning mansion or palace, and it has been used as a place-based given name. Because it points directly to a stately dwelling, the name carries immediate associations of status, residence, and rooted place.
The name feels very short and very Welsh, with a clean, compact sound. Plas is unusual as a personal name, which makes it striking, but its meaning is simple and concrete. It suggests prestige through geography rather than through ornament.
