I get them confused sometimes. They're so close in spelling that if you aren't careful the switch can sneak up on you. I try to remember to pronounce advise in head with a hard "z" so it sounds more like an action. I don't know if that makes sense but it worked for me.
No. Advice is what I give, advise is what I do. Advice is a noun, advise is a verb transition. " I gave the woman advice about her marital conflict." " I advised her to seek legal counsel regarding separation." " I would advise her to speak to her attorney about her alternatives."
