Variable words their definition and examples in detail

Variable words

The variable words are all those that support gender and number morphemes, called inflections. That is, these will change depending on whether what we want to express is feminine, masculine, singular, or plural. This will require concordance between them with other elements of the sentence. The variable words are:

  • Determinants
  • Adjectives
  • Verbs
  • Nouns
  • Pronouns

1-The determinants, variable words

The determinants always accompany nouns, therefore incorporate variations and inflections to agree in gender and number with them. We use determiners when we want to specify the meaning of the name with which they go. which are words that will always accompany a noun. In this way we can find the following:

  • Articles: An example. The fence of the farm is brown.
  • Demonstrative : This, this, that … For example, the following sentenceThat table is free.
  • Undefined : Some, none, any … For example. Some ship was able to cross the strait despite the storm.
  • Questions and exclamations : What, how much … We find an example in the following sentence. ¿ What color is your favorite?
  • Numerals : One, two, first … Let’s see an example. It is the first time that I am going to see a musical.
  • Possessives : My, you, our… Let’s see an example. Your brother is very handsome .

2-The adjectives

Adjectives are variable words that show the qualities of a noun, therefore they will always accompany the name. These will always agree in gender and number with the first. In addition to this agreement, within adjectives we can find different degrees. Next we are going to see some examples, but you can learn much more in this lesson in which we delve into it.

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

3-The verb

The verb is the core of the verb phrase l. It is a variable word that admits inflectional morphemes of number, person, time, aspect and mode. Through the different verb tenses we can clearly see the forms they take. Next we are going to see some examples included in these sentences:

  • Alba is hungry.
  • The tank is full, so we can leave whenever you want.
  • The woman was the only one who remained inside the bus when it reached the last stop.
  • The lights in his house are on.
  • The neighbors were tired of the noise caused by the train as it passed near their houses.
  • Miguel told us about what he had done last summer.


The nouns are those variables words we use to name people, animals, things, qualities or ideas. As we have already advanced, these can incorporate inflectional morphemes related to gender and number. Nouns can be divided into the following types:

  • Own : Alba was very excited about her new project .
  • Singles : The cat hid in the corner.
  • Countless : His father has a very peculiar humor .
  • Accountants : Just give me a chop , please.
  • Concretes : The dining room is very large.
  • Commons : The boy is doing his homework.
  • Collectives : The wolf pack rested by the river.
  • Abstract : His evil is infinite.

5-The pronouns

Pronouns are variable words that we use when we want to substitute for a noun. By using them we achieve better communication since we avoid unnecessary repetitions. These, because they are going to replace the name, acquire the same functions as it. Within the pronouns we can find the following

  • Demonstrative . This, that, that, this … Pay attention to this example. This is the one I want.
  • Undefined . Someone, something, nothing … In this sentence you will find the following example. Some decided to raise their voices at the threat.
  • Interrogative and exclamatory . What, how much, who… Let’s look at an example. ¿ Who was?
  • Personal : I, you, him, we… Let’s see an example. I ‘m going to see him tomorrow .
  • Relative . What, who, which … An example. The men we saw in the park are my neighbors.
