First of all, in order to focus on examples of sentences with an indeterminate subject, we must know what a subject is. The subject is the noun phrase, the noun or the pronoun that agrees in person and number with the verb . The subject, therefore, is required in a mandatory way by the verb.

The subject is always made up of a noun phrase. That is, the subject will always have as its nucleus a noun, a substantiated word or a pronoun. Due to this, it must always agree in number and person with the verb that it refers to within the sentence.

Within the subject we can find different types that fall into two large categories:

• Lexical or explicit subject: the subject is shown explicitly within the sentence, that is, we can easily see it.
• Subject understood or implicit : the subject does not appear written in the sentence, but we can know that it is and is understood by the verb that accompanies it. Examples of sentences with indeterminate subject

In turn, within these we can find different subtypes such as the ones we will see below.

Subjects can be grouped into different categories taking into account the way they appear in the sentence. Thus, within the second category, that of implicit subjects, we will find the following subtypes:

• Elliptical or omitted subject : in these cases the subject does not appear in the sentence we are analyzing because it has already done so before. Therefore, to avoid unnecessary repetitions, it is decided to eliminate it. On the other hand, this can also appear expressed through verbal morphemes.
• Indeterminate Subject : the indeterminate subject occurs when this part is omitted in a sentence. It can occur for two reasons, because it has been deliberately decided to eliminate it or because the speaker does not know who is the subject who performs or suffers the action of the verb. The subject, therefore, must be sought in a referential way since we do not have it written.

At this point where we already know what the subject is, the types that exist and what indeterminate subjects are, we are going to show you some examples of these so that you can easily identify them and know how to analyze them correctly in a sentence. Pay attention to the following sentences in which the subject does not appear expressly.

• They say that the consequences of the events that happened yesterday will be very serious.
• In this case, we do not see what the subject is, the sender of the sentence does not know either. In this case, it is omitted due to lack of information to determine who fulfills this function. Let’s see more examples like the one above:
• They robbed the mall tonight .
• The price of gasoline has dropped .
• The crime weapon could not be found .
• There is no reason to believe that this will be the case.
• There was a monumental traffic jam in the city center due to the football game.
• The area was surveyed for clues that could aid the investigation.
• Waiter is needed . Examples of sentences with indeterminate subject
