The sentence 'She don't like apples' is grammatically correct.
True
False
The correct contraction for 'does not' with third-person singular is 'doesn't', not 'don't'. 'She doesn't like apples' is the correct form. Contractions must agree with the subject in person and number.
In English, most adverbs end in '-ly'.
True
False
Many English adverbs are formed by adding '-ly' to adjectives, like 'quick' to 'quickly'. However, there are exceptions such as 'fast' and 'well'. The rule applies to a large number of adverbs, making it generally true.
The word 'their' is a possessive pronoun.
True
False
'Their' indicates possession and modifies a noun without an apostrophe. It is used to show ownership by multiple people. It differs from 'there' (place) and 'they're' (they are).
The past participle of 'go' is 'goed'.
False
True
The irregular verb 'go' has the past participle 'gone', not 'goed'. Irregular verbs do not follow standard '-ed' endings. Always check irregular verb lists when in doubt.
An adjective modifies a noun.
False
True
Adjectives describe or limit nouns by providing attributes like size, color, or quantity. For example, 'blue car' uses 'blue' to modify 'car'. Adjectives can appear before nouns or after linking verbs.
In English questions, the auxiliary verb comes after the subject.
True
False
In yes/no questions, auxiliaries like 'do', 'have', or modal verbs appear before the subject: 'Do you like it?' For wh-questions, the wh-word precedes the auxiliary. This inversion is a key feature of English question structure.
The phrase 'less people' is correct usage when comparing countable nouns.
False
True
'Fewer' is used with countable nouns ('fewer people'), while 'less' is for uncountable quantities ('less water'). Confusing these is a common mistake. Remember countable vs. uncountable rules.
Every sentence must have a subject and a verb to be complete.
True
False
A complete sentence typically requires at least a subject and a finite verb to express a full thought. Fragments lack one of these and are incomplete. Even imperative sentences have an implied subject.
The subjunctive mood in English uses 'were' for all subjects.
True
False
In hypothetical or contrary-to-fact clauses, English uses 'were' for all subjects (I were, he were). This is the subjunctive mood and is retained in formal styles. It indicates unreality or wish.
A dangling modifier occurs when the modifier doesn't clearly refer to any word in the sentence.
True
False
A dangling modifier is a phrase that doesn't attach clearly to any word, causing confusion: 'Walking down the street, the trees were beautiful.' The modifier seems to describe the trees, not the walker. It must be rewritten.
In English, infinitives always take the preposition 'to'.
True
False
Bare infinitives appear without 'to' after modals (can go), let, make, and sense verbs. Not all infinitives require 'to'. Understanding when to drop 'to' is essential.
Split infinitives are universally accepted in formal English.
False
True
Though split infinitives (to boldly go) are widely accepted in modern usage, some formal styles still discourage them. The debate continues, but they are not universally accepted in all formal contexts.
Noncount nouns can be made plural by adding 's'.
False
True
Noncount (mass) nouns like 'information' and 'rice' do not take an 's' to make them plural. They refer to substances or concepts. Count nouns take plural forms.
The Oxford comma is mandatory in all forms of English writing.
False
True
The Oxford (serial) comma is optional and style-dependent. American academic and some publishing styles prefer it; others omit it. It is not grammatically mandatory.
In indirect speech, tense shifts are optional.
True
False
Indirect (reported) speech typically requires backshifting the tense (present to past) unless the reporting verb is in the present or the statement is still true. Tense shifts are not optional in standard usage.
A semicolon can join two independent clauses without a coordinating conjunction.
True
False
Semicolons may join two closely related independent clauses without 'and' or 'but'. For example: 'I came; I saw.' This use shows a stronger connection than a period.
Restrictive clauses should be set off by commas.
False
True
Restrictive (essential) clauses are necessary to identify the noun and therefore are not set off by commas. Nonrestrictive clauses, which add extra information, use commas. Example: 'The book that I borrowed was good.'
The pronoun 'who' should be used for people, while 'which' should be used for things.
False
True
'Who' refers to people and 'which' to animals or things. Using the correct relative pronoun clarifies meaning. Some style guides allow 'that' for restrictive clauses of people and things.
Collective nouns are always treated as singular in American English.
False
True
In American English, collective nouns (team, committee) are usually singular ('The team wins'), but can be plural if emphasizing individual members. British English more commonly uses plural agreement.
The word 'data' is universally considered singular.
False
True
'Data' is technically the plural of 'datum', but usage varies. In scientific contexts, it's often plural ('The data are clear'), while in general usage it's treated as a singular mass noun.
The past perfect tense is formed by 'had' plus the past participle.
True
False
The past perfect indicates an action completed before another past action: 'She had left before I arrived.' It uses 'had' plus the past participle. This distinguishes two past events.
Prepositions at the end of sentences are considered incorrect in formal writing.
False
True
Modern grammar accepts terminal prepositions when they sound natural ('Who are you talking to?'). The 'no preposition at end' rule is a prescriptive holdover. Clarity and flow are priorities.
Gerunds can function as subjects, objects, or complements in a sentence.
True
False
Gerunds (verb+ing) act like nouns. They can be subjects ('Swimming is fun'), objects ('I enjoy swimming'), or subject complements ('Her favorite activity is swimming'). Their versatility is characteristic.
The subjunctive form of 'to be' in 'If I were you' is an example of the independent subjunctive.
False
True
In 'If I were you,' 'were' is an independent subjunctive expressing a hypothetical situation. The independent subjunctive appears outside subordinate clauses and often follows verbs like 'suggest' or 'demand.' This form is rare but correct.
In 'Not only did he sing, but he also danced,' the inversion creates a compound sentence.
True
False
The sentence uses inversion for emphasis on 'Not only' and coordination with 'but'. It remains a single compound structure, not two separate clauses joined by inversion. Inversion affects word order, not clause type.

Cheat Sheet

  1. Subject-Verb Agreement -

    In any grammar true false quiz, matching subjects and verbs in number and person is essential. For example, "Neither of the answers is correct" follows the rule that singular subjects take singular verbs (Purdue OWL). Use the mnemonic "SV=1+1=2" to remind yourself that a single subject pairs with a single verb.

  2. Correct Use of Lay vs. Lie -

    True or false grammar questions often trip students up on verbs like "lay" and "lie." According to the Cambridge Grammar of the English Language, "lay" requires a direct object ("I lay the book down"), while "lie" does not ("I lie down"). Remember: you lay something down, but you lie down yourself, a handy tip for any English grammar test.

  3. Pronoun-Antecedent Agreement -

    In a grammar quiz online setting, ensuring pronouns agree with their antecedents in gender and number is vital. Oxford University Press emphasizes avoiding vague references, e.g., "Every student must bring their book" should be "his or her." Try the trick "pronoun points back" to ensure clarity in your grammar challenge quiz.

  4. Proper Punctuation with Clauses -

    True or false grammar questions often hinge on comma usage between independent and dependent clauses. The Modern Language Association (MLA) style guide instructs using a comma before coordinating conjunctions linking two independent clauses ("I wanted to study, but I was tired"). Recall the "FANBOYS" acronym (for, and, nor, but, or, yet, so) when tackling punctuation in an English grammar test.

  5. Active vs. Passive Voice Recognition -

    Identifying active and passive constructions is a staple of any grammar true false quiz. The University of Chicago's writing guidelines suggest preferring active voice for clarity ("The researcher conducted the experiment" instead of "The experiment was conducted by the researcher"). Use the tip "doer first" to spot active sentences quickly in your grammar challenge quiz.
