I learn more words from spell check. Just now, my email client suggested “cavicorn” instead of favicon. So earnest. “Do you mean cavicorn?” I wish I did, spell check. But I don’t know anyone who has hollow horns, or how I would use that trait in a metaphor.
This is really just an excuse to tell the internet about the time my spell check suggested I edit a love letter to read “Dear hognuts.” I let that suggestion come up a few times before I finally added hotnuts to the dictionary.
