Practice or practise?

The yoga essay says the WHO mYoga app supports yoga practice and encourages people to practise yoga. Did you notice the two spellings? On page 125 your book, Poorvi, explains them.

PRACTICE, with a c, is a NOUN: the name of a thing. It means the regular doing of a skill. We say 'a regular practice of stretching', 'a lot of practice', 'a daily practice'. A clue: a noun often has 'a', 'the', 'my' or 'a lot of' before it.

PRACTISE, with an s, is a VERB: an action word. It means to do something again and again to get better at it. We say 'I practise yoga every day', 'the coach asked us to practise running', 'she practises the piano'.

Another pair works the same way. ADVICE (with a c) is a noun: 'My grandfather gave me good advice.' ADVISE (with an s) is a verb: 'The doctor advised me to rest.' A trick to remember: c for the noun, s for the verb.
