Rifle given popular outlaw’s name (5)
I believe the answer is:
robin
'outlaw's name' is the definition.
'Robin' can be an answer for 'name' (name for men or women). I'm not sure about the 'outlaw's' bit.
'rifle given popular' is the wordplay.
'rifle' becomes 'rob' (rifle can mean to steal or rob).
'given' says to put letters next to each other.
'popular' becomes 'in' (something that's 'in' is fashionable).
'rob'+'in'='ROBIN'
Can you help me to learn more?
(Other definitions for robin that I've seen before include "Small brown and red bird" , "See 12" , "Christmas songbird" , "Day was one" , "Hood, Goodfellow or redbreast?" .)
