So true! There are so many exceptions to the rules, and words are adopted from different European languages.
We’ll begin with box; the plural is boxes;
But the plural of ox is oxen, not oxes,
One fowl is a goose, and two are called geese,
Yet the plural of moose is never called meese.
You can find a lone mouse or a house full of mice;
But the plural of house is houses not hice.
The plural of man is always men.
But the plural of pan is never pen.
If I speak of a foot, and you show me two feet,
And I give you a book, would a pair be a beek?
If one is a tooth and a whole set are teeth,
Why shouldn’t two booths be called beeth?
If the singular’s this and the plural is these,
Should the plural of kiss be ever called keese?
We speak of a brother and also of brethren,
But though we say mother, we never say methren.
When the masculine pronouns are he, his, and him;
Just imagine the feminine….she, shis, and shim!
