Fret about wading bird seen by river (6)
I believe the answer is:
regret
'fret' is the definition.
The answer and definition can be both to do with human feelings as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'wading bird seen by river' is the wordplay.
'wading bird' becomes 'egret' (egret is a kind of wading bird).
'seen by' is a charade indicator (letters next to each other).
'river' becomes 'r'.
'egret' after 'r' is 'REGRET'.
'about' acts as a link.
Can you help me to learn more?
(Other definitions for regret that I've seen before include "Feel repentant" , "Feel sad or disappointed about" , "Feeling or repentance or sorrow" , "Bad feeling" , "Feel repentance or disappointment" .)
