If you want to add some text, or if you want some text to float with the curve of another element (such as clipart or logo), make your letter curve along a path in Word quite easy.  First, click on "Insert" on the main word band.
Click on "WordArt" from the text options.
Choose the style you want WordArt to be.
Enter your text in your newly selected WordArt box.
With your new WordArt you are still selected. Click on "Format" on the main word band.
Click the "Text Effects" button.
Click on "Transform" from the drop-down menu.
To get your text to follow a curved path, you want to select one of the options in the "Follow Road" section of the menu. You can choose if you want the text to curve up, down or around.
Click to make your selection and you'll see the text automatically inclined in the direction you choose 
To play with the degree of your curve, drag the orange dot .
By moving the orientation of the orange dot, adjust the curve of your text. You can also use it to turn your text upside down. You need to play the format and adjustments a bit to get your text curved just the way you want, especially if you try to match it with another object.
If you want your text to return to normal without curves, return to the Text Effects menu and press "No transform."
Just like that, your text is back to normal.
