Comprehensive vocabulary flashcards covering clauses, phrases, parallel structure, sentence types, modifiers, punctuation rules, and common grammatical errors from Grade 8 ELA review notes.

Noun Clause

A dependent clause that functions as a noun—acting as a subject, object, or complement—often beginning with words like whoever, what, that, or whichever.

Nonrestrictive Adjective Clause

An adjective clause providing extra, non-essential information that is set off with commas.

Restrictive Adjective Clause

An adjective clause essential to the meaning of the sentence that does not use commas.

Participial Phrase

A phrase that describes a noun and acts as an adjective.

Gerund Phrase

A phrase built around a verb form ending in -ing that acts as a noun (such as the subject of a sentence).

Infinitive Phrase

A phrase consisting of 'to' plus a verb that can act as a noun, adjective, or adverb.

Appositive Phrase

A phrase that renames a noun, set off with commas when it provides extra (nonrestrictive) information.

Absolute Phrase

A phrase modifying the whole sentence rather than a single noun, usually consisting of a noun plus a participle with no true verb.

Adverb Clause of Concession

An adverb clause using markers like 'even though,' 'although,' or 'while' that admits a contrasting point before the main clause.

Reducing a Clause to a Phrase

Shortening a clause containing a subject and verb into a concise phrase without losing the sentence's meaning.

Faulty Parallelism

An error where a sentence mixes different grammatical forms within a list or series; fixed by rewriting every item to match the same form.

Parallel Structure in Comparison

The grammatical rule requiring both sides of a comparison using 'than' or 'as' to share the exact same grammatical form.

Parallel Structure with Correlative Conjunctions

The requirement that the grammatical forms following each part of a correlative pair (such as 'not only / but also' or 'either / or') must match.

Sentence Openings (Subordinate Clause & Participial Phrase)

Techniques used by writers to vary sentence beginnings by starting with a subordinate clause or a participial phrase instead of always opening with the subject.

Compound-Complex Sentence

A sentence containing at least two independent clauses and at least one dependent clause.

Misplaced Modifier

A modifier positioned in the wrong place in a sentence, resulting in an unclear or unintended meaning.

Dangling Modifier

A modifier that describes a word or target that is not actually present in the sentence.

Subordinating Conjunction for Logical Relationship

Choosing a specific conjunction to accurately indicate how two ideas relate, such as showing cause, contrast, time, or condition.

Concise, Active Style

A writing approach that eliminates wordy phrases (such as replacing 'due to the fact that' with 'because') to favor active, direct sentences.

Colon for Explanations and Formal Quotations

A punctuation mark used after a complete independent clause to introduce an explanation or a formal quotation.

Semicolon with Conjunctive Adverbs

A punctuation structure where a semicolon links two independent clauses before a conjunctive adverb (e.g., 'however,' 'therefore'), followed by a comma.

Semicolons in a Complex Series

The use of semicolons to separate items in a list or series when the individual items already contain internal commas.

Subject-Verb Agreement with an Adjective Clause

Ensuring the main verb correctly agrees in number with the true subject of the sentence, even when an adjective clause intervenes between them.

Comma Splice

A grammatical error in which two independent clauses are joined with only a comma and no coordinating conjunction.

Fixing a Comma Splice

Methods of resolving a comma splice by adding a coordinating conjunction, changing the comma to a semicolon, or separating the clauses into two distinct sentences.
