Stitch up Cockney dwelling south of area that's outstanding (7)
I believe the answer is:
awesome
'outstanding' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'stitch up cockney dwelling south of area' is the wordplay.
'stitch' becomes 'sew' ('sew' can be a synonym of 'stitch').
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'cockney dwelling' becomes 'ome' ('home' - 'home' can be a synonym of 'dwelling' - said with the 'H' dropped - a cockney accent.).
'south of' is a charade indicator (letters next to each other).
'area' becomes 'a' (maths abbreviation).
'sew' written backwards gives 'wes'.
'wes'+'ome'='wesome'
'wesome' after 'a' is 'AWESOME'.
'that's' is the link.
Can you help me to learn more?
