Hoskins goes to a party with grass producer (6)
I believe the answer is:
meadow
'grass producer' is the definition.
'meadow' can be an answer for 'grass' (thesaurus). I am unsure of the 'producer' bit.
'hoskins goes to a party with' is the wordplay.
'hoskins' becomes 'me' (where the crossword setter is 'Hoskins').
'goes to' means one lot of letters go next to another.
'party' becomes 'do' (do can informally mean a party).
'with' becomes 'w' (abbreviation).
'me'+'a'+'do'+'w'='MEADOW'
Can you help me to learn more?
(Other definitions for meadow that I've seen before include "Grassy field" , "Field used for hay" , "Seventeen dn used for hay" , "somewhere grassy" , "Low ground near river" .)
