We’ll begin with a box, and the plural is boxes;
But the plural of ox should be oxen not oxes.
One fowl is a goose, but two are called geese,
Yet the plural of moose should never be meese.
You may find a lone mouse or a nest full 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?
