practice? practise?

英式英文:
practice係noun解練習/實行
例:Learning a language needs a lot of practice.

practise係verb都係解練習/實行
例:The young girl practises the violin every day.
I don't think you practice enough.

不過美式英文裡面好似verb同noun都係用practise

typing mistake...should be 'I don t think you practise enough'

pratice(noun):doing an activity to improve your skill練習
practise(verb): to do an acivity to improve your skill練習

美式是noun and verb 都用pratise.
記唔到就記住prat[ice]<---noun////pract[ise]<---not a noun
