Enough - it's broken fine cutting saw (10)
I believe the answer is:
satisfying
'enough' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?
'it's broken fine cutting saw' is the wordplay.
'broken' is an anagram indicator.
'fine' becomes 'f' (abbreviation e.g. condition of old coins, books).
'cutting' means one lot of letters goes inside another (some letters cut their way into a word).
'saw' becomes 'saying' (a saw can mean a proverb or maxim).
'its' anagrammed gives 'tis'.
'tis'+'f'='tisf'
'tisf' put into 'saying' is 'SATISFYING'.
Can you help me to learn more?
(Other definitions for satisfying that I've seen before include "Meeting (a condition)" , "Cool" , "Meeting (needs, etc)" , "Fulfilling (a need)" , "enough?" .)
