About this topic

Grammar terminology has a reputation for being fussy, which is unfair to it. The labels exist for the same reason a mechanic names the parts of an engine: it is much easier to say what is wrong with a sentence when you can point at the piece causing the trouble. These ten cover the parts of speech, a few clause types and the punctuation marks that cause most of the arguments. Where a supposed rule is actually a matter of taste rather than grammar, the explanation says so.

  1. 1A word such as "heavy" or "blue", which describes a noun, is called what?

    • A An adverb
    • B A pronoun
    • C A conjunction
    • D An adjective Correct

    Answer: D. An adjective

    Why: Adjectives modify nouns, while adverbs do the same job for verbs, adjectives and other adverbs. English usually puts adjectives before the noun, whereas French and Spanish more often place them after it.

  2. 2In the sentence "She posted the letter", which part is the direct object?

    • A Posted
    • B The
    • C The letter Correct
    • D She

    Answer: C. The letter

    Why: The direct object is the thing the verb acts on, so it is the letter, with "she" as the subject and "posted" as the verb. Verbs that take no object at all, such as "arrive", are called intransitive.

  3. 3What does a preposition do?

    • A Marks the tense of a verb
    • B Shows how a noun relates to another word, often in place or time Correct
    • C Joins two clauses of equal weight
    • D Replaces a noun mentioned earlier

    Answer: B. Shows how a noun relates to another word, often in place or time

    Why: In, on, under, before and despite are all prepositions. The rule against ending a sentence with one was imported from Latin grammar and has never described English well.

  4. 4The apostrophe in "the dog's bowl" is doing which job?

    • A Marking possession Correct
    • B Marking a plural
    • C Marking a contraction
    • D Marking emphasis

    Answer: A. Marking possession

    Why: It signals that the bowl belongs to the dog. The other job of an apostrophe is standing in for missing letters, as in "don't", and ordinary plurals never need one.

  5. 5A verb in the passive voice does what?

    • A Places the action in the present moment
    • B Expresses a wish or a condition
    • C Joins two independent clauses
    • D Puts the receiver of the action into the subject position Correct

    Answer: D. Puts the receiver of the action into the subject position

    Why: "The window was broken" is passive, while "someone broke the window" is active. The passive is useful when the doer is unknown or beside the point, which is why it is so common in scientific writing.

  6. 6What is a semicolon most commonly used for?

    • A Marking a pause inside a phrase
    • B Showing that words have been omitted
    • C Joining two closely related complete sentences Correct
    • D Introducing a list

    Answer: C. Joining two closely related complete sentences

    Why: It links two statements that could each stand alone but read better together. Its other job is separating items in a list when the items already contain commas.

  7. 7In "the cat that sat on the mat", what kind of clause is "that sat on the mat"?

    • A A noun phrase
    • B A relative clause Correct
    • C A main clause
    • D A conditional clause

    Answer: B. A relative clause

    Why: A relative clause modifies a noun and usually opens with who, which or that. It cannot stand alone as a sentence, which is what separates it from a main clause.

  8. 8An irregular verb is one that does what?

    • A Forms its past tense without adding -ed Correct
    • B Cannot take an object
    • C Has no infinitive form
    • D Changes meaning in the plural

    Answer: A. Forms its past tense without adding -ed

    Why: Go becomes went and bring becomes brought, with no -ed in sight. Irregular verbs in English are mostly very old and very common words, and heavy use is exactly what protects them from being tidied up.

  9. 9What is the infinitive form of an English verb?

    • A The form ending in -ing
    • B The past participle
    • C The third-person singular form
    • D The base form, usually written with "to" in front of it Correct

    Answer: D. The base form, usually written with "to" in front of it

    Why: To walk and to be are infinitives. The old objection to splitting one, as in "to boldly go", came from Latin, where the infinitive is a single word and physically cannot be split.

  10. 10A collective noun refers to what?

    • A A noun that cannot be counted
    • B A noun formed from a verb
    • C A group treated as a single unit Correct
    • D Two nouns joined by a hyphen

    Answer: C. A group treated as a single unit

    Why: Team, flock and committee are all collective nouns. British English often treats them as plural, as in "the team are winning", while American English usually keeps them singular.
