I previously posted about using advisor vs. adviser, but I neglected to share the tricky difference between advice vs. advise. Let me advise you, shall I?
Advice vs. Advise
advice = an opinion about how to solve a problem; guidance (noun)
advise = to offer advice; to counsel (verb) pronounced advize
Please give me some advice about what to do.
Please advise me about what to do. (The act of advising is an action or verb.)
