Flier allowed to have a cry? (5)
I believe the answer is:
owlet
'flier' is the definition.
(owlet is a kind of birdanimal)
'allowed to have a cry?' is the wordplay.
'allowed' becomes 'let' (to let is to allow or permit).
'to' says to put letters next to each other (I've seen this in other clues).
'have a cry?' becomes 'ow' (I can't explain this - if you can you should give a lot more credence to this answer).
'let' after 'ow' is 'OWLET'.
Can you help me to learn more?
(Other definitions for owlet that I've seen before include "Young bird; moth" , "Junior member of parliament" , "new hooter?" , "Small bird of prey from Africa and Asia" , "Small hooter" .)
