Could this possibly come from electronic store? (6)
I believe the answer is:
stereo
'could this possibly come' is the definition.
The definition suggests a singular noun which matches the answer.
'from electronic store?' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'electronic' becomes 'e' (as in e-mail or e-books).
'e'+'store'='estore'
'estore' anagrammed gives 'STEREO'.
(Other definitions for stereo that I've seen before include "Two-channel sound" , "Three-dimensional sound effect, in short" , "Twin-channel sound" , "Tape recorder" , "Record-player" .)
