Nearly all cycle wearing current leisure wear (6)
I believe the answer is:
bikini
'leisure wear' is the definition.
'bikini' can be an answer for 'wear' (bikini is a kind of wear). I am not certain of the 'leisure' bit.
'nearly all cycle wearing current' is the wordplay.
'nearly all' means to remove the last letter.
'cycle' becomes 'bike' (bike is a kind of cycle).
'wearing' becomes 'in' (as in being 'in' certain clothes).
'current' becomes 'I' (symbol for electric current).
'bike' with its last letter removed is 'bik'.
'bik'+'in'+'i'='BIKINI'
Can you help me to learn more?
(Other definitions for bikini that I've seen before include "gear in two pieces" , "Two piece swimsuit" , "revealing clothing" , "practised here with explosive results" , "Beach clothing" .)
