Writer Dante mostly one to hang around? (7)
I believe the answer is:
pendant
'one to hang around?' is the definition.
(a pendant hangs around one's neck)
'writer dante mostly' is the wordplay.
'writer' becomes 'pen' (something which writes).
'mostly' means to remove the last letter.
'dante' with its final letter removed is 'dant'.
'pen'+'dant'='PENDANT'
(Other definitions for pendant that I've seen before include "Hanging jewellery item" , "earring, say" , "Hanging light" , "Ornament hanging from necklace" , "One hung by the neck" .)
