Common Agreement and Relationship Errors

Errors involving agreement and grammatical relationships are among the most common problems in English writing. They often occur because learners focus on words that are close to the verb or pronoun rather than identifying the actual grammatical relationship.

Subject–Verb Errors

Incorrect:

❌ The list of items are ready.

Correct:

✓ The list of items is ready.

The subject is list, not items.

Agreement with Each and Every

Incorrect:

❌ Every student have a book.

Correct:

✓ Every student has a book.

Every normally takes a singular countable noun and singular agreement.

Errors with Indefinite Pronouns

Incorrect:

❌ Everyone are responsible.

Correct:

✓ Everyone is responsible.

Although everyone refers to multiple people conceptually, it is grammatically singular in standard agreement.

Pronoun Case Errors

Incorrect:

❌ Between you and I, this is difficult.

Correct:

✓ Between you and me, this is difficult.

The preposition between requires an object form.

Ambiguous Pronoun Reference

Unclear:

When Sara met Maria, she was carrying a file.

The reader cannot immediately determine who she refers to.

Clearer:

When Sara met Maria, Sara was carrying a file.

Agreement Across Long Sentences

Long phrases between the subject and verb can make agreement difficult:

The introduction of new regulations concerning imported goods has created difficulties.

The subject is introduction, not goods.

A useful editing technique is to temporarily remove intervening phrases:

The introduction has created difficulties.

Faulty Parallel Relationships

Grammatical relationships should also remain parallel:

❌ She likes reading, swimming, and to cycle.

Better:

✓ She likes reading, swimming, and cycling.

Parallel structure makes relationships between elements easier to understand.

Logical Agreement

Grammar must sometimes reflect meaning as well as form:

The police are investigating the matter.

Police normally takes plural agreement in standard English.

Similarly:

Mathematics is difficult for some students.

Although mathematics ends in -s, it normally takes singular agreement because it is treated as a singular subject.

The Core Principle

Good agreement depends on identifying the real grammatical relationships within a sentence:

Who is the subject?
What is its number and person?
What does each pronoun refer to?
Is a word an object, complement, or adverbial?
Are related elements structurally parallel?

Once these relationships are understood, many apparently difficult grammar problems become much easier to analyze and correct.
