I'm a little stuck... Click here to teach me more about this clue!

'lawyer' is the definition.
The answer and definition can be both people as well as being singular nouns.

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for barman that I've seen before include "Drinks server" , "One employed to serve" , "He serves drink" , "Male who serves in a pub" , "he might be responsible for you getting shot" .)
