Other irregular plural nouns (the I-umlaut/I-mutation)

The word foot is an irregular plural noun (it does not end in -s/-es; such as, books). Besides this, it demonstrates the I-mutation/I-umlaut (pronounced uhm-lout) Sounds complicated. Not to worry; it’s mostly smoke in mirrors. See the chart:


The I-mutation effect is seen in the swapping of vowels from singular to denote the plural: foot we spell as feet, to mean more than one foot; goose (sing.) goes to geese (pl.); and tooth (sing.) is teeth (pl.) But then, why does moose stay moose in both pl. and sing. noun forms? That’s because English, as a language, makes no sense. Welcome to the English language.

Just kidding.

Moose comes from the Algonquian (likely, from the Narragansett which is present day Rhode Island). So, the Algonquian people probably didn’t observe the same rules as the PIE (Proto-Indo-European) Western Germanic family of languages. This is a speculation, albeit a reasonable one to draw.

The reason we can assume this, however, is precisely because moose is moose and not meese. Goose, foot, and tooth are all Germanic words (they come from the Germanic languages of PIE), and the Germanic languages incepted the I-mutation (as far as we’re aware) to denote a plural, i.e., more than one of something.
