I believe the answer is:

hosts

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

'entertainers' is the definition.
(host is a kind of entertainer)

I cannot understand how the rest of the clue works.

(Other definitions for hosts that I've seen before include "Acts as compere" , "Shots fired at party givers" , "Multitudes" , "Great numbers of those who entertain?" , "Landlords" .)

I've seen this clue in The Times.
