After five, is it in good taste to be calling in? (8)
I believe the answer is:
visiting
'to be calling in?' is the definition.
(I've seen this before)
'after five is it in good' is the wordplay.
'after' means one lot of letters go next to another.
'five' becomes 'V' (Roman numeral).
'good' becomes 'g' (abbreviation).
'v' next to 'is' is 'vis'.
'vis'+'it'+'in'+'g'='VISITING'
'taste' is the link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for visiting that I've seen before include "Staying as a guest" , "Gin visit (anag.)" , "Calling to see" .)
