Meaning one in Paris could be bother (9)
I believe the answer is:
importune
'be bother' is the definition.
Although both the answer and definition are verbs in their base form, I don't understand how one could define the other.
'meaning one in paris' is the wordplay.
'meaning' becomes 'import' (synonyms).
'one in paris' becomes 'une' ('one' in French).
'import'+'une'='IMPORTUNE'
'could' acts as a link.
Can you help me to learn more?
(Other definitions for importune that I've seen before include "Harrass with persistent requests" , "Persistently request" , "Demand" , "Harass" , "Hound" .)
