Practise or practice?

[FloralGums]

I really don’t understand when to use practice/practise.

Do I practice or practise my reverse parking?
Do I do piano practice or practise?

Do my children need to do their spelling practice or practise and do they practice or practise their spellings? Is there a difference between the two?

I do understand it’s a doctor’s practice.

Help!

Autocorrect is probably using US English. In British English ‘practicing’ is not a word.

@redgingerbread great thank you, I was trying to use that as way to remember which way round was the verb and noun (hoping my phone would recognise practicing not being a word!) will have to use my brain instead.

I had a shorthand teacher who said that the key to remember is that practise is a doing word (verb) so has the s for sex which is something you do! And practice is a noun so a thing/object so has a c for ... !

I was in my early 20s and at the time thought she was an elderly lady so was super shocked by her example - but it worked I never forgot about it.

Looking back over 30 years later she was probably in her 40s so not too old for the 'doing word' that she seemed to be at the time!

Maybe it helps you to think of where they go in the sentence. Most sentences are a subject - verb - object construction.
nouns go into the subject or object position.
verbs go into the verb position.
The subject = who /what is doing the action
verb= the action
object = who/what is undergoing the action.

my daughter (subject (and noun)) walks (verb) the dog (object (and noun)).

To show you that nouns are not always physical things that you can touch:
my daughter (s /noun) feels (verb) sad (o /noun)
my daughter (s/ noun) is breathing (verb) air (o/noun)

Now to use practise /practise:
my daughter (s/noun) practises (verb) her spelling practice (o/ noun)
my daughter (s/n) had to go (v) to the doctor’s practice (o/n)
The doctor (s/n) advised (v) she do more spelling practice (o/n)
I (s/n) am practising (v) my piano practice (o/n).

It might also help you to substitute practise /practise with a verb like “walk” to figure out if you are dealing with a noun or verb.
so in you example above (“go and practise you spelling”) you can substitute practise with walk (“go and walk…..), meaning you need the verb in this particular sentence. In a different sentence (“ do your spelling practice”) you cannot substitute practice with walk (“do your spelling walk” incorrect).
