I understand that one is a noun and one is a verb. But is it correct to say "There is no band practice today" or "There is no band practise today"

UPDATE: I am not asking for the correct spelling of the word "practice" or "practise". The dictionary definition is clear. I am asking which usage is correct in this example sentence.

  • Not duplicate. In that example "Practice amp" is clearly a noun. Thus the dictionary definition of the word provides a clear answer. – Jacob Mar 20 '19 at 12:46
  • If practice is clearly a noun (an attributive noun, functioning as an adjective), then practise must be a verb. In your sentence, band is the attributive noun and practice the noun. – Andrew Leach Mar 20 '19 at 12:47
