Collective nouns are names for a collection or a number of people or things. Words like group, herd, and array are collective noun examples. Here, we’ll take a closer look at collective nouns, and provide even more examples, placing them in context so you can gain a greater understanding of how they work.
A mass noun is a noun (such as advice, bread, knowledge, luck, and work) that names things that in English cannot usually be counted. A mass noun (also known as a noncount noun) is generally used only in the singular. Many abstract nouns are uncountable, but not all uncountable nouns are abstract.
