Prettiest Words: A Work in Progress
The first one gave me pause; the person who constructed the list might like the way it sounds, but "abattoir" is not a pretty concept.
Here are a few other similar lists (fair warning, some of them appear to be copied content from other sites):
- The 100 Most Beautiful Words in English (I've seen the same list in several places, don't know the originator)
- 100 Beautiful and Ugly Words (this one seems to offer something of a value judgment in which words are on which list)
- Survey Identifies Most Pretty and Ugly Words in English Language (argh, it's "prettiest" and "ugliest")
