Anew means once more, and from the beginning. Not carrying on — starting over.
It is a formal and rather literary word, and it almost always follows a verb: begin anew, start anew, build anew. That is its whole grammar, and it never comes before the thing it describes. Everyday English says again or all over again instead. It belongs to the small family of a- words that keep an older shape, alongside afresh, which means almost exactly the same thing and sounds slightly less grand.
