You'll recall the difference between nouns and verbs. Nouns are objects, concepts, things. Verbs are "doing words", words that indicate some sort of action. For example, squirrel is a noun, and run is a verb.
So, where does this come into play with advice and advise?
Quite simply these two words, separated by that single letter (C or S), are two forms of the one concept.
Advice is a NOUN. It means "recommendations, suggestions, guidance". It is pronounced "ad-vice".
Advise is a VERB. It means "recommend, offer suggestions about the best course of action, give guidance". It is pronounced "ad-vize", with a "z" sound at the end.
So you would advise (verb) your friend to get some financial advice (noun) when they are looking to buy an evil lair, for example.
My hint on how to remember the difference?
advISE = verb
advICE = noun — and ice (as in frozen water) is a noun, a thing. So look for the ICE in advICE, and you'll have no problem remembering that it's a noun as well.
Keep in mind that the noun, advice, never changes form — it is a plural already, so you don't ever say "advices". A lot of advice, a tiny bit of advice, and even a ton of advice, yes, but never advices.
Advise, however, being a verb, has several forms: advised, advising, advises, and so on.
Here are some example to practise on. See if you can figure out which form to use in each sentence, either advice or advise. The verb advise may appear in different forms (advises, advised, etc). Then check your answers below! Don't peek!
