Another way to greet a water-bird (5)
I believe the answer is:
egret
'bird' is the definition.
(egret is a kind of bird)
'another way to greet' is the wordplay.
'another way' indicates an anagram.
'greet' is an anagram of 'EGRET'.
'a water' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for egret that I've seen before include "One wading" , "Heron-like wader" , "Bird eating fish" , "Kind of white heron - greet it" , "Greet (anag) -- wading bird" .)
