Spear seabird we hear (6)
I believe the answer is:
skewer
'spear' is the definition.
(skewer can mean to spear or pierce)
'seabird we hear' is the wordplay.
I cannot really see how this works, but
'we' is found in the answer.
The remaining letters 'sker' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for skewer that I've seen before include "Kebab holder" , "Transfix" , "Pin for food" , "more asymmetrical?" , "Stick on which kebab is cooked" .)
