Old man in Rome with extra time for sales pitch (6)
I believe the answer is:
patter
'sales pitch' is the definition.
(thesaurus)
'old man in rome with extra time' is the wordplay.
I cannot really understand how this works, but
'man' could be 'pat' and 'pat' is found in the answer.
'time' could be 't' (abbreviation) and 't' is found within the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for patter that I've seen before include "Light tapping sounds as of little feet" , "Line of gab" , "Light repetitive sounds - little feet or rain" , "Sound of quick light taps, rain or little feet" , "See 1" .)
