Scottish churches start to kill nettles (5)

I believe the answer is:

kirks

I'm a little stuck... Click here to teach me more about this clue!

'scottish churches' is the definition.
'kirks' can be an answer for 'churches' (kirk is a kind of church). I'm not sure about the 'scottish' bit.

'start to kill nettles' is the wordplay.
'start to' indicates taking the first letters.
'nettles' becomes 'irks' (I've seen this in another clue).
The first letter of 'kill' is 'k'.
'k'+'irks'='KIRKS'

Can you help me to learn more?
