The name Quair has a Brittonic etymology. It may be derived from the element *wejr (<*wẹ:drā) meaning "a bend, something curved or twisted" (c.f. Middle Welsh gweir, Welsh gwair, gwŷr; in compounds). The name could also descend from *wẹ:Σ- or *wiΣ, both forms of the root *wei which has a basic sense of "flowing", with the suffix –urā-.
