Formal reception on the embankment? (5)
I believe the answer is:
levee
This clue might be a double definition.
'formal reception' is the first definition.
'levee' can be an answer for 'reception' (I've seen this before). I am not certain of the 'formal' bit.
'the embankment?' is the second definition.
(I've seen this before)
'on' acts as a link.
Can you help me to learn more?
(Other definitions for levee that I've seen before include "Flood embankment" , "Riverside embankment" , "Gathering" , "Morning reception once held by monarch" , "River bank reinforcement, particularly in the US" .)
