A noun that is real or physical
This type of noun does not use a capital letter unless it is appearing at the start of a sentence and is a noun that is the general name of an object (not used to identify a specific person, thing, or place)
A proper noun is used to talk about a specific person, item or place. The proper noun always uses a capital letter, whether it appears at the beginning, middle or end of the sentence. (Ex. a person's name, city, state, etc.)
An abstract noun is used to refer to something which is not tangible or phrases are not things which can be physically sensed.
Countable nouns are individual objects, people, places, etc. which can be counted.
Uncountable nouns are substances, concepts, materials, information, etc. that cannot be divided into separate elements. They can’t be counted.
A collective noun is used to refer to a collection of things or people. A collective noun is used to refer to a singular verb as though it is one thing.
Compound nouns are words for people, animals, places, things, or ideas, made up of two or more words. Most compound nouns are made with nouns that have been modified by adjectives or other nouns.
Possessive nouns are nouns that show ownership or possession. Normally these words would be a singular or plural noun, but in the possessive form they are used as adjectives to modify another a noun or pronoun.
Most singular nouns are made plural by adding -s to the end of the singular form.
When a noun ends in a sibilant sound – /s/, /x/, /z/, /ch/, /sh/ or /ss/ – the plural is formed by adding -es, or -s if the singular already ends in -e.
The plural form of some nouns that end in ‘f’ or ‘fe’ is made by changing the ending to -v(es).
When a noun ends in “o” preceded by a consonant, the plural in many cases is spelled by adding -es.
Nouns that end in ‘o’ preceded by a vowel are made plural by adding -s.
When the ‘y’ follows a consonant, changing ‘y’ to ‘i’ and adding -es.
When the ‘y’ follows a vowel, the plural is formed by retaining the ‘y’ and adding -s.
Irregular plural nouns are nouns that do not become plural by adding -s or -es, like most nouns in the English language do. Instead, it forms a new word.
For example, the plural form of man is men, not mans. The plural form of woman is women, not womans.
