In English, most nouns are made plural by adding an "-s" or "-es" at the end of the word. For example, "book" becomes "books" and "watch" becomes "watches." However, there are some exceptions.

Words ending in "-y" replace the "y" with an "i" and add "-es." For example, "baby" becomes "babies" and "city" becomes "cities." Similarly, some words ending in "-o" also add "-es" instead of just "-s," such as "potato" becoming "potatoes" and "tomato" becoming "tomatoes."
