Which sentence is correct?
She don't like coffee.
She doesn't likes coffee.
She doesn't like coffee.
She don't likes coffee.
In English, third-person singular verbs require an auxiliary 'does' when forming negatives and questions. 'She doesn't like coffee' correctly uses 'doesn't' plus the base form 'like.' The other options either omit the correct auxiliary or misuse verb agreement. Proper subject-verb agreement ensures clarity and correctness. For more details, see .
Which sentence is correct?
There going to the store.
Theres going to the store.
They're going to the store.
Their going to the store.
The contraction 'they're' stands for 'they are,' which matches the intended meaning of the sentence. 'Their' is a possessive pronoun, and 'there' refers to a place, so both are incorrect here. Choosing the correct homophone is crucial for clear writing. See more at .
Which sentence is correct?
It's raining outside.
Its raining outside.
Its' raining outside.
Its raining outside'.
The contraction 'it's' combines 'it is,' which is appropriate when stating weather conditions. 'Its' without an apostrophe is a possessive pronoun, and the other forms misplace the apostrophe. Correct punctuation ensures your meaning is understood. For further explanation, see .
Which sentence is correct?
I have less books than you.
I have few books than you.
I have fewer books than you.
I have lesser books than you.
Use 'fewer' for countable nouns like 'books' and 'less' for uncountable quantities. 'Fewer books' correctly indicates comparison of individual items. Mixing them up is a common error. To learn more, see .
Which sentence is correct?
Whom did you called at the party?
Whom did you call at the party?
Who did you call at the party?
Who did you called at the party?
In formal English, 'whom' serves as the object of a verb or preposition. 'Whom did you call' correctly uses 'whom' as the object of 'call.' The other options misuse the object form or verb agreement. For more on use of whom, see .
Which sentence is correct?
He and I went to the movie.
Me and him went to the movie.
He and me went to the movie.
Him and me went to the movie.
Subject pronouns 'he' and 'I' are correct when they function as the subjects of a sentence. 'He and I went to the movie' places the pronouns properly in subject case. Using 'him' or 'me' in subject position is incorrect. See for more.
Which sentence is correct?
She has already eaten dinner.
She have already eaten dinner.
She had already eaten dinner.
She has already ate dinner.
The present perfect tense requires 'has' plus the past participle. 'She has already eaten dinner' correctly pairs 'has' with the past participle 'eaten.' The other options misuse either the auxiliary or the verb form. For detailed tense usage, consult .
Which sentence is correct?
Please choose whether cheese or crackers.
Please choose between cheese and crackers.
Please choose between cheese or crackers.
Please choose whether cheese and crackers.
Use 'between' with 'and' when presenting two alternatives. 'Between cheese and crackers' is the correct idiom. 'Whether' is used for indirect questions or choices followed by 'or.' Proper conjunction choice ensures clarity. See for more.
Which sentence is correct?
Neither the manager nor the employees are available.
Neither the manager or the employees were available.
Neither the manager nor the employees were available.
Neither the manager nor the employees was available.
With 'neither...nor,' the verb agrees with the noun closest to it. Here 'employees' is plural, so the plural verb 'were' is correct. The other choices misapply subject-verb agreement or conjunction usage. For more examples, see .
Which sentence is correct?
Each of the students has completed their homeworks.
Each of the students have completed their homework.
Each of the students have completed his homework.
Each of the students has completed their homework.
When 'each' is the subject, it takes a singular verb. 'Each of the students has completed their homework' pairs 'each' with 'has.' The use of 'their' is acceptable as a singular gender-neutral pronoun in modern usage. For more on pronoun agreement, visit .
Which sentence is correct?
The committee have reached its decisions.
The committee has reached its decision.
The committee have reached its decision.
The committee has reach its decision.
In American English, collective nouns like 'committee' are singular and take singular verbs. 'The committee has reached its decision' is correct. British English can differ, but the singular usage is standard here. For more, see .
Which sentence is correct?
If I am you, I would apologize.
If I was you, I would apologize.
If I were you, I would apologize.
If I are you, I would apologize.
The subjunctive mood for unreal or hypothetical situations uses 'were' with all subjects. 'If I were you' expresses a hypothetical condition correctly. The other forms either misuse the subjunctive or fail to convey hypotheticals. For more on subjunctive usage, see .
Which sentence is correct?
She is one of the people who always helpful.
She is one of the people who are always helpful.
She is one of the people who is always helpful.
She is one of the people which are always helpful.
In the clause 'who are always helpful,' 'who' refers to 'people,' which is plural, so the plural verb 'are' is correct. Using 'is' would incorrectly treat 'who' as referring to 'she.' Non-defining pronouns must agree with their antecedents in number. See more at .
Which sentence is correct?
He ran quick to the store.
He ran quicklyly to the store.
He ran quickly to the store.
He quick ran to the store.
Adverbs ending in -ly modify verbs, so 'quickly' is correct here. 'Quick' is an adjective and cannot modify a verb. The other forms either misuse suffixes or parts of speech. Proper adverb usage improves clarity. For more, see .
Which sentence is correct?
The cat who was hungry, meowed loudly.
The cat, which was hungry meowed loudly.
The cat, which was hungry, meowed loudly.
The cat, who was hungry, meowed loudly.
A nonrestrictive clause adds extra information and is set off by commas. Using 'who' for an animal in a nonrestrictive clause is acceptable, and the commas around the clause are correctly placed. Omitting or misplacing commas changes meaning or creates fragments. See for guidance.
Which sentence is correct?
I look forward to meet you.
I am looking forward meet you.
I look forwards to meeting you.
I look forward to meeting you.
After the phrase 'look forward to,' the gerund form is required. 'Meeting' correctly functions as a gerund. Using the infinitive 'to meet' or adding an extra 's' to 'forward' is incorrect. Proper verb form usage ensures fluency. For more, see .
Which sentence is correct?
Having finished the assignment, the TV was turned on.
He having finished the assignment, the TV was turned on.
Having finished the assignment, he turned on the TV.
The TV having finished the assignment, it was turned on.
A dangling modifier occurs when the subject of the modifying phrase doesn't match the main clause. 'Having finished the assignment, he turned on the TV' correctly links the action to the person. The other sentences misplace the modifier, creating confusion. Proper modifier placement is key to clarity. See .
Which sentence is correct?
Only after the meeting they decided to proceed.
They decided only after the meeting to proceed.
After only the meeting did they decide to proceed.
Only after the meeting did they decide to proceed.
When 'only' starts a clause that triggers inversion, the auxiliary verb precedes the subject. 'Only after the meeting did they decide...' correctly inverts 'did' and 'they.' The other options either fail to invert or misplace 'only.' For more on inversion, see .
Which sentence is correct?
The data is conclusive.
The data is conclusives.
The data are conclusive.
The data are conclusiving.
In formal usage, 'data' is the plural form of 'datum' and takes a plural verb. 'The data are conclusive' reflects this standard. Informal usage may treat 'data' as singular, but formal writing prefers the plural. For a deeper dive, see .
Which sentence is correct?
He is one of the few who understands quantum mechanics.
He is one of the few who understand quantum mechanics.
He is one of the few who understood quantum mechanics.
He is one of the few who understanding quantum mechanics.
The relative clause 'who understand quantum mechanics' refers to 'few,' which is plural. Therefore, the plural verb 'understand' is correct. Using 'understands' would incorrectly treat the clause as singular. Proper agreement in complex sentences is essential. See .
Which sentence is correct?
I wish I will be more patient.
I wish I am more patient.
I wish I were more patient.
I wish I was more patient.
The subjunctive mood after 'wish' requires 'were' to express a hypothetical or contrary-to-fact condition. 'I wish I were more patient' follows this rule. The other forms misuse tense or mood. For additional examples, see .
Which sentence is correct?
This is the most unique example we have.
This is a very unique example we have.
This is the unique example we have.
This is the most uniquely example we have.
The adjective 'unique' is absolute and does not take comparative or superlative forms. 'This is the unique example we have' correctly states that there is only one example. Other constructions either misuse modifiers or create redundancy. For more on absolute adjectives, see .
Which sentence is correct?
He suggested that she attends the conference.
He suggested her to attend the conference.
He suggested that she to attend the conference.
He suggested she attend the conference.
After verbs like 'suggest,' English uses the subjunctive in that-clauses or omits 'that' and uses the base verb. 'He suggested she attend the conference' correctly applies the subjunctive. The other options misuse infinitives or present tense. For more, see .
Which sentence is correct?
I have a principal problem with that idea.
I have a principle problem with that idea.
I have a principle problematic with that idea.
I have a principle problems with that idea.
The adjective 'principal' means 'main' or 'most important,' while 'principle' is a noun. 'A principal problem' correctly uses the adjective form. Misusing these homophones leads to confusion. For more, see .
Which sentence is correct?
If he had known, he would have informed us earlier.
If he had knew, he would have informed us earlier.
Had he knew, he would have informed us earlier.
If he would have known, he would have informed us earlier.
The third conditional expresses a past unreal situation with 'if' plus past perfect and 'would have' plus past participle. 'If he had known, he would have informed us earlier' is correct. The other options misuse tense or past participle forms. For more on conditionals, see .
Which sentence is correct?
Rarely I have seen such a beautiful sunset.
Rarely have I seen such a beautiful sunset.
Rarely have I saw such a beautiful sunset.
Rarely I seen such a beautiful sunset.
Starting a sentence with 'rarely' triggers subject - auxiliary inversion. 'Rarely have I seen' correctly inverts 'have' and 'I.' The other options either omit inversion or misuse verb forms. Such inversion lends emphasis in formal writing. For more, see .
Which sentence is correct?
Between you and I, this is confidential.
Between you and myself, this is confidential.
Between you and me, this is confidential.
Between you and me, this confidential.
After prepositions like 'between,' object pronouns are required. 'Between you and me' correctly uses 'me' rather than the subject form 'I.' 'Myself' is a reflexive pronoun and cannot replace the object pronoun here. See for more.

Cheat Sheet

  1. Subject-Verb Agreement Mastery -

    Matching subjects and verbs in number is a cornerstone of proper English, as noted by Purdue OWL. Isolate the true subject before selecting which one is the correct verb form (e.g., The list of items is long vs. The items are long). Frequent drills in which you identify and correct the sentence with answers will solidify this skill.

  2. Comma Usage and the Oxford Comma -

    Commas clarify meaning and can even change it, so the Cambridge Grammar of English stresses knowing when to use the Oxford comma. Remember the FANBOYS mnemonic (for, and, nor, but, or, yet, so) to spot coordinating conjunctions that need commas. Practice marking where commas belong and decide which sentence is correct to sharpen your punctuation.

  3. Pronoun-Antecedent Alignment -

    Every pronoun must agree in number and gender with its antecedent, a rule emphasized by the British Council. In sentences like "Neither Gina nor her friends brought their own snacks," test if this sentence is grammatically correct by checking agreement. Regular exercises in identifying mismatches will boost your confidence on any English language grammar quiz.

  4. Active vs. Passive Voice Clarity -

    The University of North Carolina Writing Center recommends using active voice for more direct, engaging prose. Compare "The researcher conducted the experiment" (active) with "The experiment was conducted by the researcher" (passive) to see which sentence is correct in context. Rewriting passive constructions into active ones helps you internalize clear, impactful writing.

  5. Distinguishing Commonly Confused Words -

    Merriam-Webster notes homophones like their/there/they're are frequent quiz traps. Use the mnemonic "There points to a place, their shows possession, they're is they are" to cement the difference. As you correct the sentence with answers, you'll never mix these up again.
