Ring the Parisian in boat being loaded (7)
I believe the answer is:
opulent
'being loaded' is the definition.
(I've seen this before)
'ring the parisian in boat' is the wordplay.
'ring' becomes 'o'.
'the parisian' becomes 'le' (definite article in French).
'in' indicates putting letters inside.
'boat' becomes 'punt' (I've seen this before**).
'le' placed within 'punt' is 'pulent'.
'o'+'pulent'='OPULENT'
(Other definitions for opulent that I've seen before include "Wealthy, got lots of money" , "Wealthy, rich" , "Ostentatiously rich" , "Rich, luxuriant" , "extremely elegant" .)
