Singular Plural Tangle

We’ll begin with a 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 many find a lone mouse or a house full of mice,

But the plural of house is houses, not hice.

If I speak of a foot and you show me two feet,

And I give you a book, would a pair be a beek?

We speak of a brother and also of brethren,

But though we say mother, we never say methern.

Then the masculine pronouns are he, his and him;

But imagine the feminine…she, shis and shim!
