A few clever lines causing riots, perhaps, in a cricket club (8)

I believe the answer is:
acrostic
'a few clever lines causing' is the definition.
I can't tell whether this defines the answer.
'riots perhaps in a cricket club' is the wordplay.
'perhaps' indicates an anagram.
'in' is an insertion indicator.
'cricket club' becomes 'cc' (cricketing abbreviation).
'riots' is an anagram of 'rosti'.
'a'+'cc'='acc'
'rosti' put within 'acc' is 'ACROSTIC'.
Can you help me to learn more?
(Other definitions for acrostic that I've seen before include "Word puzzle using first letters" , "problem" , "Socratic sort of word puzzle" , "Bit of wordplay" , "Initial letter puzzle" .)
