I love the word pretty.
A theory: “Pretty” has gone out of favor because we are greedy, and want the merely pretty to be fully beautiful, and so we go around calling things beautiful that are pretty.
There’s something self-flattering about it — describing a thing as beautiful makes the speaker appear more sensitive to beauty. Conversely, “pretty” always sounds like an understatement, and as such can actually be more flattering to the thing described.
