Rudely ignore old person on a boat (9)
I believe the answer is:
gondolier
'person on a boat' is the definition.
The definition and answer can be both people as well as being singular nouns.
I also know that 'boat' relates to this answer.
'rudely ignore old' is the wordplay.
'rudely' is an anagram indicator (rude can mean rough or unrefined).
'ignore'+'old'='ignoreold'
'ignoreold' with letters rearranged gives 'GONDOLIER'.
Can you help me to learn more?
(Other definitions for gondolier that I've seen before include "Singular SO" , "One to move over water" , "Venetian boater" , "Punter" , "Craftsman" .)
