Trip sporting idol in the grass (7)
I believe the answer is:
holiday
'trip' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'sporting idol in the grass' is the wordplay.
'sporting' indicates an anagram.
'in the' indicates putting letters inside.
'grass' becomes 'hay' (hay is dried grass).
'idol' anagrammed gives 'olid'.
'olid' inserted within 'hay' is 'HOLIDAY'.
Can you help me to learn more?
(Other definitions for holiday that I've seen before include "Vacation" , "Billie" , "Break from work" , "given a break" , "rest" .)
