Parts of Speech, Syntax & Punctuation Mechanics
The Writing subtest rigorously tests your ability to identify grammatical elements in context and detect common mechanical errors.
1. The 8 Parts of Speech
- Noun: Person, place, thing, or abstract idea (e.g. teacher, school, curriculum, patience).
- Pronoun: Replaces a noun (e.g. he, she, it, they, who, everyone).
- Verb: Expresses action or state of being (e.g. write, listen, is, were).
- Adjective: Modifies or describes a noun or pronoun (e.g. diligent student, quiet room).
- Adverb: Modifies a verb, adjective, or other adverb (e.g. read attentively, very bright).
- Preposition: Shows relationship in time or space (e.g. on the desk, during recess, under the table).
- Conjunction: Connects words, phrases, or clauses (e.g. and, but, although, because).
- Interjection: Expresses strong emotion (e.g. Wow!, Ouch!).
2. High-Frequency Sentence Boundary Errors
- Comma Splice: Two complete sentences joined only by a comma (e.g. "The bell rang, the students stood up." Fix: add "and" or use a period/semicolon).
- Sentence Fragment: A dependent clause or phrase lacking a main independent subject and verb (e.g. "Because the rain started suddenly." Fix: attach to an independent clause).
Step-by-Step Worked Practice Problem

- Identify the true grammatical subject: "stack" (singular).
- Identify and eliminate intervening prepositional phrases: "of student essays".
- Match the singular subject with the singular verb: "The stack ... is ready."
- Answer: The correct verb is "is".

Frequently Asked Questions
When should I use a semicolon instead of a comma?
Use a semicolon to link two independent clauses that are closely related in thought when no coordinating conjunction (FANBOYS) is used.
Why is 'each of the students brought their book' considered informal?
In formal standard English, 'each' is singular and requires a singular pronoun ('his or her book').
