One doubts I can go dancing around street (8)
I believe the answer is:
agnostic
'one doubts' is the definition.
(I've seen this before)
'i can go dancing around street' is the wordplay.
'dancing' is an anagram indicator.
'around' is an insertion indicator.
'street' becomes 'st' (abbreviation).
'i'+'can'+'go'='icango'
'icango' is an anagram of 'agnoic'.
'agnoic' placed around 'st' is 'AGNOSTIC'.
(Other definitions for agnostic that I've seen before include "Coasting as one who believes the mind cannot know anything of a god" , "Doubter of God" , "One believing we can know nothing of the existence of any god" , "A non-believer in God, coasting along" , "One holding that knowledge of God is impossible" .)
