Nonconformist spirit laid back, unconventional I mean (8)
I believe the answer is:
bohemian
'nonconformist' is the definition.
(I know that bohemian is a type of nonconformist)
'spirit laid back unconventional i mean' is the wordplay.
'spirit' becomes 'hob' (hob is a kind of spirit).
'laid back' says the letters should be written backwards.
'unconventional' indicates an anagram.
'hob' backwards is 'boh'.
'i'+'mean'='imean'
'imean' with letters rearranged gives 'emian'.
'boh'+'emian'='BOHEMIAN'
(Other definitions for bohemian that I've seen before include "of old country" , "Opera by Balfe 'The . . . . . . . . Girl'" , "Unconventional artist" , "Nonconformist" , "Unconventional type" .)
