how can I tell the 'dizzy' 'faint' and relevant words?

[Liqichao]

hello,

could you give me some words like dizzy and faint and their differences.

another question is how can I use delibrate, knowing, willful?

many thanks

dizzy - feeling unable to stand steadily, for example because you are looking down from a high place or because you are ill (The heat and the champagne made him feel dizzy.)
faint - feeling weak and as if you are about to become unconscious because you are very ill, tired, or hungry (The heat made him feel quite faint.)
I hope these examples will help you.
I think the matter is that when you feel dizzy your head is swimming. And here is one more synonym - giddy (feeling slightly sick and unable to balance, because everything seems to be moving: Greg stared down from the seventh floor and began to feel giddy.)
