Celebrity in the morning visiting Tyneside? (4)
I believe the answer is:
name
'celebrity' is the definition.
(as in a 'big name')
'morning visiting tyneside?' is the wordplay.
'morning' becomes 'am' (as in 12:00 AM).
'visiting' means one lot of letters goes inside another.
'tyneside?' becomes 'NE' (region in North East of England).
'am' put inside 'ne' is 'NAME'.
'in the' acts as a link.
(Other definitions for name that I've seen before include "Monicker" , "Famous person; reputation" , "Amen (anag)" , "Designation - reputation" , "Good reputation; specify; christen" .)
