Ten bats with red or white splice (7)
I believe the answer is:
entwine
'splice' is the definition.
(thesaurus)
'ten bats with red or white' is the wordplay.
'bats' indicates an anagram (slang for mad).
'with' means one lot of letters go next to another.
'red or white' becomes 'wine' (I've seen this in another clue).
'ten' anagrammed gives 'ent'.
'ent'+'wine'='ENTWINE'
(Other definitions for entwine that I've seen before include "closely blend together" , "Wind or twist together" , "Lace" , "knit" , "Braid" .)
