I am typing something and spellchecker keeps insisting that “mould” is not a word, which was perplexing me. So, I finally looked in the dictionary. Allegedly, “mold” is the normal American spelling, and “mould” is the normal British spelling. This claim is news to me. I have been speaking English all my life, and have always lived in the United States. I have always spelt the container that holds cooling liquid “mould”, and the fungi that grow on food “mold”. I am honestly shocked by the dictionary’s claims: both regarding “mould” being chiefly British, and regarding the container and the fungi being spelt the same. Have I really been spelling this word different than everyone around me and not noticing? Am I abnormal for using different spellings for different meanings?
How do you spell this word, and does your spelling vary according to meaning?
