Of all the English grammar concepts we have, “plural” seems to be one of the most uncomplicated. Did you get one thing? It’s singular. Got more than one thing? It’s plural. But alas, language is always less undemanding than we expect. The way we conceptualize something—as one thing or many things—doesn’t always match up with the way our word for it behaves. There are some nouns that only have a plural form, regardless of how we think of them. In this English lesson from Let's Talk English Speaking Institute in Mumbai, you will learn Nouns which are always in the plural form.
