- In English, an article (a, an, or the) is a type of determiner. Single countable nouns usually require a determiner.
- Articles are a type of descriptor as they additionally qualify a noun. The article is thus a word utilized in English grammar, to determine the definiteness of a noun.
- Articles noted issues are usually noted issues that can manifest language proficiency. An ignored mistake can influence language utilization syntactically.
- For example, The house is five years of age. (With the utilization of 'The' before the noun 'house', we figure out which particular house is being depicted.)
- The use of articles leads to the noun and it is important to keep in mind that we can never utilize a solitary countable thing alone without an article.
- To refer to a day as a holiday or to particularize the specific day, it is needed to use the articles before it.
Therefore the correct sentences would be-
It is a holiday today.
Today is a holiday. (Or Today is the holiday.)
