Conclusion
In conclusion, the parts of speech involves huge role in every language source, as well as, in English language nouns involves whole grammar stages.
The basic concept of nouns as a part of speech is that of the subject of the sentence.
The noun as a part of speech has the categorical meaning of “substance” or “ thingness”. The categorical functional properties of the noun are determined by its semantic properties. The most characteristic substantive function of the noun is that of the subject of the sentence. The function of the object is also typical of the noun as the substance word. Its other syntactic functions (attributive, adverbial and predicative) are performed with equal ease but are not the characteristic of its substantive quality. While performing the non-substantive functions, the noun essentially differs from the other parts of speech because of the transformations as a result of which the noun from various non-subject syntactic positions can be shifted into subject syntactic positions of the same general semantic value.
The findings of this study can help English language instructors, especially those who teach academic writing, gain more insights into noun modification features and encourage them to identify the complexity levels of their students’ work using hypothesized developmental stages. These insights can potentially enable the instructors to indicate what needs to be done in order to improve academic writing skills among Thai students and to fill the void and increase syntactic complexity in writing. It is hoped that the results of this study will bring about better material design with an additional focus on grammatical features such as noun postmodifiers, especially prepositional phrases postmodifying nouns, which have long been overlooked in academic writing courses. Materials or tasks that help draw students’ attention to complex phrasal features in academic prose can be incorporated to allow students to produce written work that meets an academic writing style that is internationally acceptable. Nouns play a multitude of roles within a sentence, as the subject, a direct object, an indirect object, a subject complement, or the object of a preposition in a sentence. When they are used as the name of something or someone, they are capitalised, these nouns are also referred to as proper nouns.
In addition to these facts, there are numerous types of nouns, including common nouns (used to refer to nonspecific people, concepts, places, or things), proper nouns (used to refer to specific people, concepts, places, or things), and collective nouns (used to refer to a group of people or things).

Examples: Nouns in a sentence

I’ve never read that book.
Ella lives in France.

Other types of nouns include countable and uncountable nouns, concrete and abstract nouns, and gerunds.
