Variable grammar categories with examples in detail

Variable Grammar Categories

In the first place, in order to know what the variable grammatical categories are, we must indicate what the grammatical categories are and what types there are . Each of the classes of words that have their own characteristics are considered grammatical categories. In total, there are 9 categories that in turn are included in two groups: Variable grammar categories with examples

  • Variable grammatical categories
  • Invariable grammatical categories

Types of invariable grammar categories

Thus, we can point out that the variable grammatical categories are all those to which inflectional morphemes can be added . In other words, these types of categories admit gender and number. Within the variable type, we find the following grammatical categories:

  • Nouns
  • Pronouns
  • Adjectives
  • Determinants
  • Verbs


The nouns are a grammatical category in which we find variables words used when we want to name people, animals, things, qualities or ideas. Because they admit inflectional morphemes, they have gender and number. In addition, according to their meaning, they can be divided into different types: Variable grammar categories with examples

  • Abstract : His goodness is contagious.
  • Collectives : The pack was quiet that night.
  • Commons : The boy lives in Albacete.
  • Concrete : The garden was full of flowers .
  • Accountants : We bought a wool blanket .
  • Countless : Ignacio has iron health .
  • Singles : The dog was scared.
  • Own : Beatriz is tired of her job .

2-The pronouns

Pronouns are used when we want to substitute for a noun. Like names, they will perform the same functions and will present the same particularities in terms of gender and number. Within the pronouns we can find several types:

  • Personal : I, you, him, we… Let’s see an example. I want to buy that car .
  • Relative . What, who, which … An example. The restaurant we saw online has very good reviews.
  • Demonstrative . This, that, that, this … Pay attention to this example. This guy is a machine!
  • Undefined . Someone, something, nothing … In this sentence you will find the following example. Some were late for the appointment.
  • Interrogative and exclamatory . What, how much, who… Let’s look at an example. ¿ Who is your best friend?

3-The adjectives

Adjectives are words that are used when we want to show the quality of a noun. Therefore, this variable grammatical category will always accompany a name. Because of this, you will necessarily need to agree with it in gender and number. On the other hand, within adjectives we can find different degrees. Although we are going to see some examples below, we encourage you to visit this lesson in which we delve into it.

  • Positive : when the quality is expressed without intensity, for example, The house is great .
  • Comparative : the quality is compared to another. In this case we find the comparatives of superiority (The house is bigger than the hut); Equality (the house is as big as the library); inferiority (The house is less big than the Town Hall); Superlative (The house is huge ).

4-The determinants

Within the variable grammatical categories we find the determiners that are words that will always accompany a noun. These are used when we want to better specify the meaning of the name they accompany. In this way we can find the following:

  • Articles : El, la, los … An example. The house was located on the other side of the hill.
  • Demonstrative : This, this, that … For example, the following sentence. That woman is my aunt.
  • Possessives : My, you, our… Let’s see an example. Can you lend me your pencil?
  • Undefined : Some, none, any … For example. Someday I will travel to Australia.
  • Numerals : One, two, first … Let’s see an example. Carmen was third on the admitted list.
  • Questions and exclamations : What, how much … We find an example in the following sentence. ¿ What are you telling me? Variable grammar categories with examples

5-The verb

When we want to express an action, a process or a state we resort to the verb . The verb is a variable grammatical category that has its own structure and that admits inflectional morphemes of gender and number as well as others related to time and mode. In a verb, therefore we can distinguish between: root and ending. The ending will be the one that contributes the grammatical meaning to the verb through the manner, the time, the person, the number, the aspect… etc. Let’s look at some examples of verbs included in different sentences.

  • Life is full of unforeseen events.
  • All the boys were sitting in the shade.
  • The municipal swimming pools will open their doors next July.
  • The dogs were upset from the storm.
  • Miguel was hungry.
  • Ana went to the fields in search of wild flowers to decorate her house.
