The word "slyly" looks very aesthetically pleasing. What are other handsome words (any language)?

One of my kids is named Ivy and she was the first to learn how to write it because it's one stick, two sticks, three sticks. Her under 2 year old sister was at the library once and pointed to a book and said "Ivy" and yep, that was on the spine of the book. So I love that word because it made two of my kids understand written language.
