Grammar and Sentence Correction

Grammar explains how words work together. A sentence usually needs a subject and a verb that agree.

Find the main subject and finite verb, then check parallel structure, pronoun reference and intended timing. Make one justified correction at a time.

Choose: “The children plays” or “The children play”. 1. “Children” names more than one child. 2. In the simple present, use “play” with “the children”. 3. The correct sentence is “The children play”.

The subject “children” is plural, so the simple-present form here is “play”. The singular “child” would use “plays”. Identify the actual subject rather than a nearby noun; then check tense, pronoun reference, modifier placement and parallel structure separately.

Correct: "The manager, along with her assistants, are responsible for reviewing reports and to approve budgets." Main subject manager is singular, so use is. The tasks must be parallel: reviewing reports and approving budgets. Result: "The manager, along with her assistants, is responsible for reviewing reports and approving budgets." The interrupting plural noun does not control the verb.

Look at the subject, not just the word closest to the verb. Do not change meaning merely to shorten a sentence. Acceptable grammar can vary with dialect and intended meaning; use an unambiguous rule when comparing exam options.

Tense and aspect locate an action in time and show completion or duration. Choose forms that match the sequence described, not a memorised word trigger alone.

"By the time we arrived, the meeting had begun" places the beginning before our past arrival. "The meeting began when we arrived" describes a different time relationship.

A and an introduce an unspecified singular countable noun; the identifies a particular one. A/an depends on sound rather than spelling.

Use "an hour" because hour starts with a vowel sound, but "a university" because university starts with a consonant sound. After introducing a book, "the book" can refer back to it.

Prepositions express relationships such as place, time and direction. Some verbs and adjectives conventionally take specific prepositions.

Compare "at 6 pm", "on Monday" and "in September". In "interested in science", in is the conventional complement; replacing it with on changes the standard construction.

A pronoun should have a clear antecedent and match the intended number and person. Ambiguity is often more important than grammatical agreement alone.

"Riya told Asha that she had won" is ambiguous. Rewrite as "Riya told Asha, I have won" or name the winner directly, according to the intended meaning.

Put a modifier close to what it describes. An opening participial phrase should normally describe the subject that follows it.

"Walking to school, the rain soaked Mira" wrongly makes rain the walker. "Walking to school, Mira was soaked by the rain" attaches the phrase correctly.

Items with the same grammatical role should use matching structures. Compare both sides of and, or, either/or and not only/but also.

Prefer "She likes reading, cycling and swimming" to "She likes reading, cycling and to swim". Matching forms make the list easier to interpret.

Check sentence structure, agreement, tense, reference and meaning in that order. A shorter option is not automatically correct.

"Each of the students have a ticket" becomes "Each of the students has a ticket". Each is singular; the plural noun inside the of-phrase does not change the agreement.

Find the main subject and finite verb, then check parallel structure, pronoun reference and intended timing. Make one justified correction at a time.

Correct: "The manager, along with her assistants, are responsible for reviewing reports and to approve budgets." Main subject manager is singular, so use is. The tasks must be parallel: reviewing reports and approving budgets. Result: "The manager, along with her assistants, is responsible for reviewing reports and approving budgets."
