Groan oddly on our old street, seeing rower? (9)
I believe the answer is:
gondolier
'rower?' is the definition.
(thesaurus)
'groan oddly on our old street' is the wordplay.
I cannot really see how this works, but
'on' is present in the answer.
an anagram of 'old' is 'dol' which is located in the answer.
This explanation may well be incorrect...
'seeing' is the link.
Can you help me to learn more?
(Other definitions for gondolier that I've seen before include "Craftsman" , "One to move over water" , "Venetian boatman" , "Traditional boatman of Venice" , "to leave Red Lion disorientated" .)
