Shelf where a fellow has a phone? (6)
I believe the answer is:
mantel
'shelf' is the definition.
(I know that mantel is a type of shelf)
'a fellow has a phone?' is the wordplay.
'a fellow' becomes 'man' (fellow can mean a man).
'has' means one lot of letters go next to another.
'a phone?' becomes 'tel' (short for telephone).
'man'+'tel'='MANTEL'
'where' is the link.
(Other definitions for mantel that I've seen before include "Lament over fireplace structure" , "prize-winning novelist" , "Shelf above a fireplace" , "Hilary?" , "Briefly, structure above and around a fireplace" .)
