Part of football match for Brown ending in southern state (6)
I believe the answer is:
stanza
'part of football match' is the definition.
'stanza' can be an answer for 'part' (I have seen 'Part of poem' mean 'stanza' so perhaps 'part' could also mean 'stanza'). I am not sure about the 'of football match' bit.
'brown ending in southern state' is the wordplay.
'brown' becomes 'tan' (tan is a kind of brown).
'ending' becomes 'Z' (Z is an example).
'in' means one lot of letters goes inside another.
'southern state' becomes 'sa' (I can't justify this - if you can you should believe this answer much more).
'tan'+'z'='tanz'
'tanz' placed into 'sa' is 'STANZA'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for stanza that I've seen before include "Lines often repeated" , "Section of verse" , "A verse of poetry" , "Unit of a poem" , "Group of poetic lines" .)
