In English English (as opposed to American English) 'Practice' spelled (spelt) 🤷‍♂️ with a 'c' is a noun.

'Practise' spelled with an 's' is a verb, therefore if you practise an instrument regularly, it is a verb - a 'doing something' type of word.

If you are referring to a Doctor's Practice, then the noun version should be used because you are using the word to describe a place rather than an activity.

So in my Teaching Practice, (a noun) practise (a verb) happens every day.

Confusion can arise when describing 'best Practice'.

It would perhaps be easier to adopt the American version which is 'practice' in all cases.

Does anyone care?🤓
