When I help someone, I am the helper, and he is the helpee. But surely there is a better word than this?
I guess you could say “recipient of help” or “beneficiary”, but I don’t really like either of these.
Edit: Thanks for all the great answers… I think everyone has added something useful – felt I should mark someone as correct, even though I feel I still haven’t found the perfect word.
The entity offering assistance is the server (or the servant).
The entity receiving assistance is the client.
Governments assist client states, computer servers assist client computers, professionals assist clients. Even librarians have started switching their terminology from patrons to clients.
