What's the difference between a 'phrase', an 'idiom', a 'phrasal verb', a 'saying', an 'aphorism', etc.?

What is difference between a "phrase" and an "idiom", and what are "proverbs" and "phrasal verbs"?

I don't think it's very important to know the differences between these. The important thing is to learn as much as you can, whether it be idioms, phrasal verbs, or whatever.

- "Phrase" can really describe any collection of words.

- An "idiom" is a phrase that has a specific meaning, different than you would expect based on the individual words. Look at these examples: http://www.phrasemix.com/englishphrases/tag/idioms

- "Proverbs" are famous sayings that include some kind of advice. Here's a site with some examples: http://en.proverbia.net/proverbs.asp

- "Phrasal verbs" are verbs that are made of more than one word. Something like "get over (something). " Here are a lot of examples: http://www.phrasemix.com/englishphrases/tag/phrasal-verb
