Why isn't the plural of moose meese?

No moose is a collective singular so many moose are moose, just as many sheep are sheep not 'sheeps'.

Because the word moose derives from an Algonquian language from around the 1600s. A lot of Native American languages do not have plural forms. Therefore, moose (or moz or mooz depending on which Algonquian language it is derived from) is both singular and plural.

The Umlaut Rule, used in old Germanic languages, is the cause of this. In Old English, if a singular word had a back vowel (Pronounced from the back of the throat, like "foot" or "Mouse") is followed by a front vowel (Sounds like "ee" or a long "I"), in the plural forms, the back vowel would be dropped and replaced with the front vowel. In old English, "foot" was spelled Foti (Fot-ee) and the plural dropped the "o" and replaced it with the "ee" sound. This gives us words like foot-feet, goose-geese, and mouse-mice. Because Moose is an American word, it doesn t follow this rule, and the plural remains moose.

Why isn't the plural of house...hice? Why is the plural of radius...radii ? Somewhere a mystic is climbing a mountain to sit and ponder this.

that's because English is just a weird language with exceptions. you know why isn't the plural of piano spelled pianoes instead of pianos since most words ending in consonant-"o" adds an -es? that's the same idea. why isn't the plural of roof rooves instead of roofs since the plural of knife is knives?? that's also the same idea. The creators of English just decided to make it harder and made it that way so you better cope with it.

The way how people speak, spell and write today, I think anything is "acceptable", so if we can use 4 for 'for', and c for 'c' and b4 for 'before' and u for 'you' etc, I am sure that we can now officially say that the plural of moose is now MEESE (Actually quite like it!!!)

For the same reason that the plural of "mongoose" isn't "mongeese." Go figure!

Think about this also and it will help you maybe.

If the Plural of Dice is Die, why is not the Plural of Mouse Mye

Because English is a crazy language

It stays the same, just as sheep do.
