Solitary type of cream (6)
I believe the answer is:
single
'solitary' is the definition.
(synonyms)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for single that I've seen before include "Individual - unmarried" , "A hit for one run in cricket" , "Just one - on one's own" , "Not married, just the one" , "Still miss" .)
