Like some rock artist cavorting before class? (10)
I believe the answer is:
stratiform
'like some rock artist cavorting before class?' is the definition.
I can't tell whether this defines the answer.
'artist cavorting before class?' is the wordplay.
'cavorting' is an anagram indicator.
'before' says to put letters next to each other.
'class?' becomes 'form' (form class is a kind of class).
'artist' is an anagram of 'strati'.
'strati'+'form'='STRATIFORM'
Can you help me to learn more?
(Another definition for stratiform that I've seen is " Arranged in layers".)
