Staff included a question about monkey (7)
I believe the answer is:
macaque
'monkey' is the definition.
(macaque is a kind of monkey)
'staff included a question' is the wordplay.
'staff' becomes 'mace' (mace is a kind of staff**).
'included' indicates putting letters inside.
'question' becomes 'qu'.
'a'+'qu'='aqu'
'mace' enclosing 'aqu' is 'MACAQUE'.
'about' is the link.
(Other definitions for macaque that I've seen before include "Primate" , "Long-tailed monkey" , "Monkey with a short or no tail" , "Monkey with a long face" , "Long-faced monkey" .)
