Soccer boot torn in dive (8)
I believe the answer is:
football
'soccer' is the definition.
(I know that soccer can be written as Football)
'boot torn in dive' is the wordplay.
'torn' is an anagram indicator.
'in' means one lot of letters goes inside another.
'dive' becomes 'fall' (I can't explain this - if you can you should give a lot more credence to this answer).
'boot' anagrammed gives 'ootb'.
'ootb' put inside 'fall' is 'FOOTBALL'.
Can you help me to learn more?
(Other definitions for football that I've seen before include "Gambling on soccer results" , "The beautiful game, some say" , "Team sport" , "Team game" , "Strange ballot of the game" .)
