The Importance of Enjambment in Poetry

This is the first English poem in not to rhyme. Enjambment is when it continues on to the next line before you get that, right? There's no clear punctuation or it's more that it crosses over to on the line break on the page. And and you know, part of this is he's trying to maintain some degree of iambic pentameter. I'm sorry if this is boring people, but this is actually I think relevant stuff to know to get a greater understanding.
