Night bird in outside hedges gives a loud cry (5)
I believe the answer is:
howls
'gives a loud cry' is the definition.
I can't tell whether this definition defines the answer.
'night bird in outside hedges' is the wordplay.
'night bird' becomes 'owl' (I've seen this in another clue).
'in' means one lot of letters goes inside another.
'outside' says to hollow out the word (remove centre letters) (I've seen 'outside of' mean this).
'hedges' with its centre removed is 'hs'.
'owl' inserted into 'hs' is 'HOWLS'.
Can you help me to learn more?
(Another definition for howls that I've seen is " Wails".)
