What is the difference between expression,idiom and proverb?
***** NOT A TEACHER *****
I once found some information that really helped me. I am delighted to share it with you.
1. The words do NOT reflect the actual meanings of the words.
2. "To kill two birds with one stone." (Of course, it does NOT mean to actually kill two birds with one stone.)
3. You can often change the tense of an idiom: "I killed two birds with one stone," "We will kill two birds with one stone if we ...," etc.
4. I made up this example: When I walk two miles to the supermarket, I kill two birds with one stone: I get some food and I get some exercise.
5. It is more "frozen." That is, one canNOT usually change the tense.
6. It is literal. That is to say, it means what it says.
a. "An apple a day keeps the doctor away." (If you eat an apple every day, you will not need to see a doctor, for an apple every day will keep you healthy.)
7. A proverb is usually a complete sentence.
8. A proverb usually reflects folk wisdom (that is, something that is supposed to be true about life).
