It will present no problems if beak is watery, I hear (2,5)
I believe the answer is:
no sweat
'it will present no problems if beak' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'watery i hear' is the wordplay.
I cannot quite see how this works, but
'i' could be 'a' and 'a' is found in the answer.
'watery' could be 'wet' (similar in meaning) and 'wet' is found in the leftover letters.
The remaining letters 'nos' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for no sweat that I've seen before include "Not a problem (US colloq.)" , "That's a piece of cake (anti-perspirant unnecessary!)" , "Not a problem! (informal)" , "fine" , "That's not a problem!" .)
