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.
