A noun is a word used as the name of a person, a thing, quality or action existing  or conceived  by the mind; substantive. We have different types of nouns;

A proper noun is the name of an individual person, places or as Mazi, Ikechukwu, Uchechi, Nnenna, Nwabueze,  Ngozi, Afo, Nkechi, Ihuoma, Ezinne, Ebube, Nkoli, Ifeoma, Nwamaka(Amaka), Nnamdi, Ndubuisi,  Edwin, Gladys, Melody, Nicole, Sandra, Rayness, Ellen, Anna, Christian, Fred and Eric. (Note, a lot of Igbo people answer English names. Some have Igbo names as second names which are hardly used). In extreme conditions, some have both English names as first and last names(surnames). Example  Ray Johnson.

A common noun is the name an individual object has in common with others of its class, as man, city, hill.

A collective noun is one expressing a collection or aggregate of individuals, as assembly, army.

An abstract noun is one indication a quality, as goodness, beauty.

Pronoun: A word used as a substitute for a noun such as I, he, she, that. Pronouns are referred to as being in First Person, Second Person and Third person. First Person is the person speaking; Second Person is the person being spoken to; and third person is the person being spoken about(of). Although, there are  many types of  pronouns, we will only concentrate on personal, possessive, demonstrative and interrogative pronouns:

Personal Pronouns: A personal pronoun is a pronoun that is used as a substitute for a “proper” or “common” noun. For example, in English the personal pronouns are I, you, he, she, we and they. Fortunately, in Igbo  these are easy to learn:

Possessive Pronoun: A possessive pronoun is pronoun that is used to express possession. For example, in the phrase, “My cat is hungry” the word “my” is the possessive pronoun. In Igbo the possessive pronouns are a bit tricky and requires some special  attention because the sentence structure between Igbo and English is different. Usually, the possessive pronoun comes after what is being possessed.

For instance:

Demonstrative Pronouns: A demonstrative pronoun is a word used to distinguish one thing from something else. In English the equivalents are “this, that, these and those”. In Igbo language the singular words for demonstrative pronouns  are”  “Nke a = This”; Nke ahụ = That or Nke afụ (Nke anwa) = That”. The plural version are  “Ndị a = These” and “Ndị ahu = Those” or “ Ndịa afụ(Ndị anwa)  = Those”

Interrogative  Pronouns/Relative pronouns: Interrogative Pronouns or Question words include: “Who, what, which, whose, whom, where, when and why”. Overall these are pretty easy and straight forward to learn in Igbo.
