Strand Johann Sebastian without energy (5)
I believe the answer is:
beach
'strand' is the definition.
(I've seen this in another clue)
'johann sebastian without energy' is the wordplay.
I cannot really understand how this works, but
'energy' could be 'ac' (AC is an example) and 'ac' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for beach that I've seen before include "Pebbly or sandy shore" , "Area of land sloping down to water" , "strand" , "Sandy sea shore" , "Shore area" .)
