It's incorporating a number of different elements for a diver all at sea (6)
I believe the answer is:
varied
'it's incorporating a number of different elements' is the definition.
I can't judge whether this definition defines the answer.
'a diver all at sea' is the wordplay.
'all at sea' is an anagram indicator.
'a'+'diver'='adiver'
'adiver' is an anagram of 'VARIED'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for varied that I've seen before include "Assorted, diverse" , "Miscellaneous" , "Widely different" , "Differing" , "Motley" .)
