Report of pranks primarily inflicted by English girl (6)
I believe the answer is:
trixie
'girl' is the definition.
'report of pranks primarily inflicted by english' is the wordplay.
'report of pranks' becomes 'trix' (I can't justify this - if you can you should give a lot more credence to this answer).
'primarily' indicates taking the first letters.
'by' means one lot of letters go next to another.
'english' becomes 'E' (abbreviation).
The initial letter of 'inflicted' is 'i'.
'trix'+'i'+'e'='TRIXIE'
Can you help me to learn more?
(Another definition for trixie that I've seen is " girl".)
