Recorded fragment about endless wave (8)
I believe the answer is:
enrolled
'recorded fragment about endless wave' is the definition.
I can't tell whether this defines the answer.
'recorded fragment about endless wave' is the wordplay.
'recorded fragment' becomes 'end' (end can mean a fragment or piece of something. I am not sure about the 'recorded' bit.).
'about' means one lot of letters goes inside another.
'endless' means to remove the last letter.
'wave' becomes 'roller' (roller is a kind of wave).
'roller' with its final letter taken off is 'rolle'.
'end' going around 'rolle' is 'ENROLLED'.
Can you help me to learn more?
