Idiomatic Verbs Used in English

As I was looking through the St. Martins Guide to witting trying to figure out what to write on; I came across a topic that I don't nessecarily have a problem with, but I thought was interesting. What I discovered were idiomatic verbs. These words and phrases are used frequently in the English language; but typically only natives to this language actually get the meaning of them. They are two or three word (or phrasal) verbs, and typically combined a verb with a word that appears to be a preposition or an adverb, that cannot be understood literally. To better get an idea of what idiomatic verbs are check out the examples bellow.

hand in means submit
hand out means distribute
look into means investigate
look out for means watch carefully
run away means leave without warning
walk out means abandon
want out means desire to be free of responsibility

If someone from another language were too try and interpret these saying literally they would be confused and most of the time wrong. English speaking natives, generally will give the correct or above mentioned interpretations. I thought this was an interesting topic, because I never really thought about these words in this way. I have always just assumed them not to be an issue, and everyone knew that they weren't intended to be taken literally.
