Admit there’s a metric measure in tangled tape (6)
I believe the answer is:
accept
'admit' is the definition.
('accept' can be a synonym of 'admit')
'a metric measure in tangled tape' is the wordplay.
'a metric measure' becomes 'cc' (cc is a kind of measure. I am not sure about the 'metric' bit.**).
'in' is an insertion indicator.
'tangled' indicates anagramming the letters.
'tape' anagrammed gives 'aept'.
'cc' put into 'aept' is 'ACCEPT'.
'there's' is the link.
Can you help me to learn more?
(Other definitions for accept that I've seen before include "Take up, obtain" , "Receive the gift or agree to comply" , "Receive something offered" , "Take (something offered)" , "Recognise" .)
