British friends of ours live in a lieu-dit called Le Chêne which they rather amusingly call 'the dog'. It is, of course, the '(white) oak'. Breton has a variety of equivalent forms: dervenn, derv, derf, dero or (Old Breton) dar/diri. These appear in: Kerderven, 'oak village'; Coat-Dero, 'oak wood'; and Dirinon, '(Saint) Non's oaks'. The Gaulish cassano appears in Quessoy.

In this blog we have already looked at 'ash' trees (see F is for Fresnaye) and yews (see I is for Iff).
