Derring Do

Re the query about derring do [or deering do etc.] I think this actually comes from the Welsh [though it may have come through Chaucer as someone suggested]. The Welsh for Blackbird is Deryn Du, blackbirds are cocky and self assured, one might almost say brave and fearless, and this name may thus have become associated with a brave or reckless deed, since English has borrowed from elsewhere throughout its development.
