Take the size that can accommodate an earpiece (5)
I believe the answer is:
seize
'take' is the definition.
(I know that seize is a type of take)
'size that can accommodate an earpiece' is the wordplay.
'that can accommodate' indicates putting letters inside.
'an earpiece' becomes 'e' (this might be a standard abbreviation which I don't know about).
'size' placed around 'e' is 'SEIZE'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for seize that I've seen before include "Take by force" , "Take possession" , "Snatch" , "Impound" , "Grab suddenly" .)
