There are many pairs of words that sound or look very similar, but they can mean very different things. There is no easy way around these words, you have to learn them as you can’t rely on spell checkers and the like to pick them up every time.

One such pair of words is advice/advise.

Advice: Opinion given or offered as to action, counsel; information given. (noun)

Advise: Offer advice; recommend. (verb)
I advise you to wear a hat when walking in the desert.

So I advise you to take care with words. And my advice is to learn the correct use of each word.
How can you remember which is which?

“I give you advice and I give you ice” will help you remember which word is the noun.
