Does he have a crowd of guests? (4)

I believe the answer is:

host

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

'crowd of guests?' is the definition.
'host' can be an answer for 'crowd' (both can mean a large number of people). I am not certain of the 'of guests?' bit.

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for host that I've seen before include "Pub landlord" , "Crowd-entertainer" , "Large crowd" , "lot of people" , "Myriad" .)

I've seen this clue in The Irish News.
