놓다 literally means put, despite there are other meanings if you just think of it as 'put', things will be easier. For example, 내놓다 means put out, since 내~ has meaning of 'out'. Also 가져다 놓다 means 'take and put' which means someone took something and put it here. If you know the word before 놓다, then it is possible that you can guess what the word means(I won't say exactly, because dictionary will show you a different word). In addition, meaning can change by the context.
