We have a tremendous amount of different methods available to use for expressing our thoughts and get them across to others. We often do not feel that we have time to take this in or process this, but this is rampant. The job of a determiner is to designate a specific number of a noun or to declare a clarification of what a noun refers to. The end result of any determiner is to introduce a person, place, or even a thing (noun). They are absolutely required to be involved in singular nouns, but optional when referring to plurals. The determiner is very often placed before the noun in a sentence.
There are four different types of determiners in the English language: articles, demonstratives, quantifiers, and possessives. Articles are used to point out which noun a speaker is referring to. There are only three singular articles: a, an, and the. Demonstratives are words that are used when a speaker has the ability to physical point to the noun they are referring to. The four most common demonstratives are: that, these, this, and those. When we want to indicate how much or how little we have of a noun we use quantifiers. They include words such as: less, few, many, and all. Possessives help you show ownership and it tells you the noun belongs to someone or thing. Examples of possessives are: my, your, his, her, its, and our.
