Part of badge with two numbers (3)
I believe the answer is:
pin
'part of badge' is the definition.
'pin' can be an answer for 'badge' (I've seen this in another clue). I am unsure of the 'part of' bit.
'with two numbers' is the wordplay.
'two numbers' means two replacements for 'number'.
'with' says to put letters next to each other.
'number' becomes 'pi'.
'number' becomes 'n' (n can represent any number).
'pi' put next to 'n' is 'PIN'.
Can you help me to learn more?
(Other definitions for pin that I've seen before include "Tack; fasten" , "Hold (down)" , "Flagged stick placed in golf hole" , "Secure" , "Fastener; skittle" .)
