Wound a hot-headed wild lass (5)

I believe the answer is:
slash
'wound a hot-headed wild lass' is the definition.
'slash' can be an answer for 'wound' (thesaurus). I am unsure of the 'a hot-headed wild lass' bit.
'hot-headed wild lass' is the wordplay.
I cannot really understand how this works, but
'hot' could be 'h' (abbreviation eg on taps) and 'h' is located in the answer.
an anagram of 'lass' is 'slas' which is within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for slash that I've seen before include "Reduce (a price) greatly" , "Greatly reduce (prices)" , "Cut as with a sword - /" , "Lacerate" , "something between a month and a year" .)
