Love racing off for something natural (7)
I believe the answer is:
organic
'natural' is the definition.
(similar in meaning)
'love racing off' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'off' is an anagram indicator.
'racing' anagrammed gives 'rganic'.
'o'+'rganic'='ORGANIC'
'for something' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for organic that I've seen before include "sort of farming" , "without the use of chemicals" , "Non-chemical" , "No cigar (anag.)" , "Derived from natural sources" .)
