Is the word holiday a common or proper noun?

In the English language, nouns are words that represent a person, place, thing, or idea. They can be categorized into two main types: common nouns and proper nouns. Understanding the distinction between these two types of nouns is fundamental to the study of grammar and the correct use of language.
Common Noun: A common noun is a general term that refers to a category of people, places, things, or ideas. It does not refer to a specific individual, place, or thing. Common nouns are not capitalized in English unless they are at the beginning of a sentence or part of a title. Examples of common nouns include words like "dog," "city," "tree," and "holiday."
Proper Noun: A proper noun, on the other hand, is a specific name given to a unique entity, such as a person, place, organization, or event. Proper nouns are always capitalized because they refer to a one-of-a-kind entity. Examples include "John," "Paris," "Microsoft," and "Christmas."
Now, let's apply this understanding to the word "holiday." In its most general sense, "holiday" refers to a day of festivity or celebration, or a period of vacation, and it is not associated with any specific instance. It is a broad term that can encompass a wide range of celebrations and time off, such as national holidays, religious holidays, or personal time off. Because it is a general term and not tied to a specific entity, "holiday" is a common noun.
However, there are instances where "holiday" can be part of a proper noun. For example, "Holiday Inn" is a well-known hotel chain, and in this context, "Holiday" is part of a proper noun because it refers to a specific brand and entity. But when we are talking about the concept of a holiday in general, without reference to any particular holiday or brand, it remains a common noun.
It's also worth noting that the context in which a noun is used can sometimes change its classification. For instance, if you were to say "the holiday season," you would be using "holiday" as a common noun to describe a period of time typically associated with various holidays. But if you were to say "Holiday is coming to town," and "Holiday" was the name of a person or a character in a story, then in that specific usage, it would function as a proper noun.
In conclusion, the word "holiday" is generally a common noun when it is used to refer to the concept of a day or period of festivity or time off in a non-specific manner. It becomes a part of a proper noun when it is used as part of a name for a specific entity, such as a brand or a place. The capitalization of the word can often be a clue to its classification: uncapitalized when it is a common noun and capitalized when it is part of a proper noun.

Hence it is a Common Noun. A Proper Noun is name of a particular person , Place and or thing.--Holiday' does not come under the purview of this definition. Hence it is not a Proper Noun. ... Holiday Inn is a proper noun, but --holiday-- is not.
