The Irony of Language -- Regarding Words for Having Beauty and Dignity

Just thinking about language, and how ironic it is, that we may say that one is dignified, when one has dignity/self-respect, however -- when it comes to not having self-respect -- we may not necessarily say that one is dignity-less; Much like, when we say that one if full of beauty -- we say that they are beautiful; but if we are referring to someone who is lacking in beauty, we do not say that they are beauty-less -- but rather, we refer to them as being ugly; homely; or unattractive.
