Army innkeeper (4)

I believe the answer is:

host

I believe this clue is a double definition.

'army' is the first definition.
(host is a kind of army)

'innkeeper' is the second definition.
(synonyms)

(Other definitions for host that I've seen before include "One entertaining, large number" , "Landlord; army" , "Crowd-entertainer" , "Compre" , "Entertainer of guests" .)

I've seen this clue in The Guardian and The Globe and Mail.
