Case of fortified wine chap tasted initially with water in Paris (11)
I believe the answer is:
portmanteau
'case' is the definition.
(I know that portmanteau is a type of suitcase)
'fortified wine chap tasted initially with water in paris' is the wordplay.
'fortified wine' becomes 'port' (port is a type of fortified wine).
'chap' becomes 'man' (chap can mean a man).
'initially' suggests taking the first letters.
'with' says to put letters next to each other.
'water in paris' becomes 'eau' (I've seen this in another clue).
The first letter of 'tasted' is 't'.
'port'+'man'+'t'+'eau'='PORTMANTEAU'
'of' is the link.
(Other definitions for portmanteau that I've seen before include "said to have several uses" , "Large old case" , "Word such as "bromance"" , "Trunk" , "Travelling-bag" .)
