Look up, means research, go to a source looking for an answer. Look up the phrasal verb "look up" in a good dictionary. . Look over means review, skim, read quickly, peruse, consider quickly. Look over the answers people provide and see what is common about them. That's probably the main point. This is our new housing development proposal. If you look over it, I think you will be impressed with the projected returns.

Creo que «look up» es como buscar y «look over» es como repasar, inspeccionar ...

Thank you very much for your response, Lindsey

Look up: You can physically look up. That means when your eyes are looking at the ground and then your head moves up and your eyes are looking ahead. "Look up when you're walking so you don't fall." You can look up a word/phrase/fact etc. It's very specific. You want to find the exact meaning of a word. You want to find an exact date. "I need to look up when World War II started. I can't remember the date." Look over: You can physically look over. That means you would move your head to look at an object that isn't right in front of you. "Look over there at that dog!" You would turn your head/body to look. Look over can also mean perusing, scanning, general looking at a document, person, thing, etc. "I need to look over this business plan before I say I agree with it." Going over: You can physically go over to a place. "I'm going over to my friend's house." That means you will walk/drive/etc to your friend's house. You can also go over notes, homework, documents, stories, etc. "I need to go over my study notes one more time before the test." This is VERY similar to look over. They're not always interchangeable, but very similar in meaning. Many times you can use go over to mean look over, but you can't always use look over to mean go over. "I need to look over the documents." "I need to go over the documents"-- Same. You want to teach your friend a game. "I'm going to go over the rules with you." DON'T SAY "I'm looking over the rules with you." I know this is confusing, I tried to be lengthy to give you more examples. I hope I didn't confuse you more. And to answer your question: I want to review my study book. I want to look over my study book. I want to look up a fact (remember look up is specific) in my study book. I will be going over my study book later today. Do you want to look over the study book with me?
