Suppressing anger, see water flowing through Nantes (5)
I believe the answer is:
loire
'water flowing through nantes' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'suppressing anger see' is the wordplay.
'suppressing' is a charade indicator (letters next to each other) (in a down clue, some letters go on top of others).
'anger' becomes 'ire' (ire is intense rage).
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'ire' after 'lo' is 'LOIRE'.
Can you help me to learn more?
(Other definitions for loire that I've seen before include "French river (Orleans, Tours, Nantes)" , "flower found amid vineyards" , "flower abroad" , "Current French" , "European river" .)
