World Wide Words: Dab hand
don't think they know either...
I've looked up the meaning of a dab hand (used for sb who is very good at sth) and I'm now wondering where this meaning comes from. How would you explain the meaning to a student who isn't simply satisfied with a definition
Thanks so much for any plausible answers.
They don't know either, but interesting link that I had come across earlier but had forgotten about.
