'advice' and 'advise'
We do use these two words interchangeably and which is not supposed to be so.
The two words are used according to two regional variations. i.e. America and Britain.
BrE 'advice' (NOUN)
AmE : 'advise' is either used as a verb or a noun.
To avoid this anomaly, it is better we take to the BrE, which ought to be our model of English.
