Grouse not following garden visitor (3)
I believe the answer is:
bee
'garden visitor' is the definition.
The definition and answer can be both groups as well as being singular nouns.
Maybe there's a link between them I don't understand?
'grouse not following' is the wordplay.
'grouse' becomes 'beef' (synonyms).
'not' suggests deleting specific letters.
'following' becomes 'f.' (used when citing page numbers etc).
'beef' with 'f' taken away is 'BEE'.
Can you help me to learn more?
(Other definitions for bee that I've seen before include "Flying insect (often busy)" , "Insect, may be in bonnet" , "meeting" , "Winged insect" , "Honey producer" .)
