Net and line in tangle for Liberal (7)
I believe the answer is:
lenient
'liberal' is the definition.
(thesaurus)
'net and line in tangle' is the wordplay.
'and' means one lot of letters go next to another.
'in tangle' is an anagram indicator.
'net' put after 'line' is 'linenet'.
'linenet' anagrammed gives 'LENIENT'.
'for' acts as a link.
(Other definitions for lenient that I've seen before include "Soft-hearted" , "Clement" , "'Indulgent, easy (7)'" , "Tolerant, merciful" , "Easy, soft" .)
