Footwear label top, for example, copy and illegally sell overseas (7)
I believe the answer is:
bootleg
'copy and illegally sell overseas' is the definition.
I can't tell whether this defines the answer.
'footwear label top for example' is the wordplay.
'footwear' becomes 'boot' (boot is a kind of footwear).
'top' indicates taking the first letters.
'for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
The initial letter of 'label' is 'l'.
'boot'+'l'+'eg'='BOOTLEG'
Can you help me to learn more?
(Other definitions for bootleg that I've seen before include "Of alcohol, sold illicitly" , "Smuggle liquor" , "obtained illegally" , "Illegally made (alcohol)" , "Illegal alcohol during prohibition" .)
