Actually, irregular plurals are those that don't add the final -s or -es to make the plural form, but they DO change. Some change their endings, such as knife-knives or wolf-wolves, and some change whitin the word or become a new one, such as mouse-mice or person-people.

Those nouns your teacher asked you about don't have a plural form (that's why they are usually uncountable) and they are called singularia tantum (which in Latin means "singular only").

Yes, I'm kind of a language freak
