Different tea interval organised (11)
I believe the answer is:
alternative
'different' is the definition.
(thesaurus)
'tea interval organised' is the wordplay.
'organised' indicates an anagram.
'tea'+'interval'='teainterval'
'teainterval' anagrammed gives 'ALTERNATIVE'.
(Other definitions for alternative that I've seen before include "choice between 2" , "Available as another possibility" , "One of a number of possibilities" , "One possible option" , "Substitute" .)
