Nouns

A singular noun refers to one person, place, thing or idea, whereas, plural noun refers to more than one person, place, idea or things. For example 'cat', 'house', 'book' presents singular form and to indictae more than one thing or plural form, it will be written as 'cats', 'houses' and 'books'. While forming the plural form of singular nouns, candidates must abide with the grammatical rules. 

A compound noun is a noun formed by combination of two or more nouns to create a new meaning. For example, when we combine two nouns 'air' and 'plane' it forms a compound noun 'airplane'. Other examples are:

• Bookshop: book and shop
• Rainbow: rain and bow
• Sunflower: sun and flower

Nouns are important because they talk about people, place, things or ideas. Nouns acts as foundation in a sentence by acting as subject, verb and more. Without a noun in a sentence, it would look vague and incomplete. Nouns gives identification, builds sentence, acts as subject, and provides clarity.

• Countable nouns are things that can be counted as seperate items like two books, three pencils, five students. Whereas, uncountable nouns are nouncs which cannot be counted like water, hair, milk, etc.
• Countable nouns have both singular and plural forms, whereas, uncountable nouns does not have singular or plural forms. 

This is something that depends upon the person and the context, so to identify an uncountable noun, first ask yourself: Can I count it in separate units? Does it have a plural form? If not, it's likely uncountable. For example, “furniture” cannot be made plural, and we don't say “two furniture.” We say “a piece of furniture” or “some furniture” instead.

Yes, in some cases, uncountable nouns can become countable, but it completely depends on the context of the sentence or the setting. For example, “coffee” is usually uncountable, but when referring to a serving or type, it becomes countable: like “We ordered two coffees.” Here, “coffees” refers to “cups of coffee, ” making it countable. Language often depends on how the noun is being used.

No, uncountable nouns are not always abstract. While many are like honesty, knowledge, or love, emotion, and experience, others refer to physical or tangible substances like sugar, rice, oil, and salt. “Water” is a physical substance, but it is still uncountable. So, both abstract ideas and concrete materials can be uncountable.

No, uncountable nouns cannot be used directly with numbers; to use them, you must use quantifiers or specific units of measurement. For instance, we don't say “two milks” but rather “two glasses of milk” or “a litre of milk.” Similarly, “advice” is uncountable, so we say “a piece of advice, ” not “one advice.”

Uncountable nouns are things that cannot be counted as individual units, for example, materials like water, sand, emotions like happiness, anger, and abstract concepts like information or advice are uncountable nouns. Uncountable Nouns don't have plural forms. For instance, we say "some information," not "informations." Instead of counting them, we measure or quantify them using units or expressions.

A collective noun is a word given to group of people, things or animals. Example: herd, family, flock, government and so forth.

These nouns are usually treated as a singular noun even though it refers to a group of animal, thing or people.
