Choose a path in abstract (4,4)
I believe the answer is:
take away
'abstract' is the definition.
(thesaurus)
'choose a path' is the wordplay.
'choose' becomes 'take' (synonyms).
'path' becomes 'way' (way is a kind of path).
'take'+'a'+'way'='TAKE-AWAY'
'in' is the link.
(Other definitions for take away that I've seen before include "Subtract - fast food" , "Minus" , "Remove - portable food" , "Remove - portable meals" .)
