Regulator initially blocks licence to supply E (10)

I believe the answer is:
electronic
'regulator initially blocks licence to supply e' is the definition.
I can't tell whether this defines the answer.
'regulator initially blocks licence to supply' is the wordplay.
'initially' says to take the initial letters.
'blocks' means one lot of letters goes inside another (the inside letters form a 'blockage').
'supply' is an anagram indicator (in a supple way).
The first letter of 'regulator' is 'r'.
'licence'+'to'='licenceto'
'licenceto' anagrammed gives 'electonic'.
'r' going inside 'electonic' is 'ELECTRONIC'.
Can you help me to learn more?
(Other definitions for electronic that I've seen before include "of some modern technology" , "Relating to micro-circuitry" , "Like a PC" , "using a computer?" , "Like a computer" .)
