Why English is so hard?

We'll begin with a box, and the plural is boxes.

but the plural of ox should be oxen, not oxes.

Then one fowl is goose, but two are called geese.

yet the plural of moose, should never be meese.

You may find a lone mouse, or a whole lot of mice.

but the plural of house is houses , not hice.

If the plural of man is always called men,

why shouldn't the plural of pan be called pen?

The cow in a plural may be cows or kine,

but the plural of vow is vows, not vine.

 And I speak of foot, and you show me your feet,

but I give you a boot... would a pair be called beet?

If one is a tooth and the whole set are teeth,

why shouldn't the plural of booth be called beeth?

If the singular is this and the plural is these,

should the plural of kiss be nicknamed kese?

Then one may be that, and three may be those,

yet the plural of hat would never be hose.

We speak of a brother, and also of brethren,

but through we say mother, we never say merthren.

The masculine pronouns are he, his, and him,

but imagine the feminine she, shis, and shim!

So our English, I think you'll all agree,

Is the trickiest language you ever did see.
