The special case of two very similar words with the same meaning bugs me. What's so special about feeling the urge to hurl that needs two naus+suffix words to express it? And it's not just one naus+suffix word that has the same meaning. There's a nauseous/nauseated combo, and there's also a nauseous/nauseating combo. Is it something to do with the same illustrative mechanism that causes us to have a million ways to say blowing-chunks? (This could get its series of posts. I have no idea why puking euphemisms make me laugh, I am older than 12, but 'Shouting Groceries' might be the best vomit euphemism ever.)
This pattern doesn't work with other illness-related words ending with -ous. For instance:
- Infectious. To infect someone. You can say infected, which doesn't mean the same thing, but you can't say infectiated. No infectiating.
- Contagious. Could spread disease. There's even fewer options for contagious. No contagiated. No contaged. No contagiating.
Instead, I call for a ban on all other forms of naus+suffix words. Seems like nauseous can mean anything anyway, at least this way I only have to remember how to spell one version of this word. Even if this plan does mean supporting a word which has more vowels than is healthy. Seriously, three vowels in a row? Pfft.
