Danube’s opening, according to Plato? (5)
I believe the answer is:
delta
'danube's' is the definition.
The definition and answer can be both natural objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'opening according to plato?' is the wordplay.
'opening' says to take the initial letters.
'to' means one lot of letters go next to another (I've seen this in other clues).
'plato?' becomes 'delt' (I can't justify this - if you can you should give a lot more credence to this answer).
The initial letter of 'according' is 'a'.
'a' put after 'delt' is 'DELTA'.
Can you help me to learn more?
(Other definitions for delta that I've seen before include "See Greek" , "Code word for D" , "Nile river mouth" , "Greek character" , "Multiple estuary" .)
