Pair allowed in with wristband (8)
I believe the answer is:
bracelet
'wristband' is the definition.
(synonyms)
'pair allowed in' is the wordplay.
'pair' becomes 'brace' (synonyms).
'allowed in' becomes 'let' (to let is to allow or permit. I am not sure about the 'in' bit.).
'brace'+'let'='BRACELET'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for bracelet that I've seen before include "Might Bel react badly to this jewellery?" , "Jewellery worn around the wrist" , "Ornament - handcuff (slang)" , "16 [ADORNMENT]" , "Wrist, arm adornment" .)
