I am typing up poetry, and one of the pieces is a concrete poem. Getting this into MS Word is going to take some advanced contortionist skills!
Adding a text box can sometimes provide a quick fix, but the location sometimes jumps or the spacing may be finicky. If you need to push letters (or words) up/down for positioning, check out the menu option Formatting > Font...
Under the Advanced tab, you can push each letter up or down by a specific amount. If you type out the word first, you would then highlight each letter you want to shift and make the adjustment. In this screenshot, I'm preparing to raise the position of the letter "h" after having raised "t" twice.
