Confuse with candid clues occasionally (5)
I believe the answer is:
addle
'confuse' is the definition.
(addling is a kind of confusing)
'candid clues occasionally' is the wordplay.
'occasionally' indicates alternate letters.
'candid'+'clues'='candidclues'
The alternate letters of 'candidclues' are 'ADDLE'.
'with' is the link.
(Other definitions for addle that I've seen before include "Confuse; become rotten" , "Muddle or confuse" , "Confuse - decay" , "Befuddle" , "becomes muddled" .)
