Identifying the Grammatical Error in Sentence Segments

The question asks us to find the segment of the given sentence that contains a grammatical error. The sentence provided is broken into four parts:

He organises / a children’s fair every year / and his friends comes / to attend it.

We need to examine each segment carefully to check for any mistakes related to grammar rules, such as subject-verb agreement, tense, articles, prepositions, etc.

Breaking Down the Sentence Structure

Let's look at the sentence segments one by one:

• Segment 1: He organises
• Segment 2: a children’s fair every year
• Segment 3: and his friends comes
• Segment 4: to attend it.

Analyzing Grammatical Errors in Each Segment

We will now analyze each segment for grammatical correctness.

Segment 1: He organises

This segment contains the subject "He" (singular third person) and the verb "organises" (simple present tense, singular form). In simple present tense, for singular third-person subjects (He, She, It, singular noun), we add '-s' or '-es' to the base form of the verb. The verb 'organise' becomes 'organises'. This segment follows the rules of subject-verb agreement for singular subjects in the simple present tense. This segment is grammatically correct.

Segment 2: a children’s fair every year

This segment describes what he organises and how often. "a children's fair" is a noun phrase acting as the object, and "every year" is an adverbial phrase of time. The use of the article 'a' before 'fair' is appropriate. The possessive 'children's' is also correct. This segment, as a phrase, is grammatically sound in this context.

Segment 3: and his friends comes

This segment joins two clauses using the conjunction "and". The subject of the second clause is "his friends". "Friends" is a plural noun, and thus the subject "his friends" is plural. The verb used is "comes". In the simple present tense, for plural subjects (I, You, We, They, plural nouns), the verb takes its base form without adding '-s' or '-es'. The base form of the verb 'come' is 'come'. Therefore, the correct form for the plural subject "his friends" should be "come", not "comes". This segment violates the rule of subject-verb agreement.

The subject "his friends" is plural, but the verb "comes" is the singular form. This is a clear grammatical error.

Segment 4: to attend it.

This segment is an infinitive phrase "to attend" followed by the pronoun object "it". This phrase acts as an adverbial phrase indicating the purpose (why his friends come). This segment is grammatically correct within the structure of the sentence.

The Grammatical Error Explained: Subject-Verb Agreement

The error is in subject-verb agreement. This fundamental rule in English grammar states that the verb in a sentence must agree in number with its subject.

• If the subject is singular, the verb must be singular.
• If the subject is plural, the verb must be plural.

In the simple present tense, for most verbs:

• Singular subjects (He, She, It, one friend) take the base verb + s/es (e.g., comes, organises).
• Plural subjects (I, You, We, They, friends) take the base verb (e.g., come, organise).

In segment 3, the subject is "his friends", which is plural. The verb form used is "comes", which is the singular form. The correct plural form is "come".

The grammatically correct sentence segment should be: and his friends come

Conclusion: Identifying the Error Segment

Based on our analysis, the segment with the grammatical error is "and his friends comes". The error is in the subject-verb agreement, where a singular verb form ("comes") is used with a plural subject ("his friends").

Additional Information: Common Grammatical Mistakes

Understanding subject-verb agreement is crucial for correct English grammar. Other common grammatical errors include:

• Incorrect use of tenses (e.g., using past tense for a present action).
• Errors with articles (a, an, the).
• Incorrect use of prepositions (in, on, at, for, etc.).
• Pronoun agreement errors (pronouns must agree in number and gender with the noun they replace).
• Misplaced modifiers (phrases or clauses that are not placed close to the word they modify).

Practicing sentence analysis and identifying the subject and verb in different sentence structures can help improve your understanding of these rules and avoid common grammatical errors.
