ACT English Editing Study Guide
Strengthen grammar, punctuation, sentence clarity, organization, and rhetorical choices through explained practice.
Topic Overview
Read enough context to decide
Some edits concern a single verb or punctuation mark, but others depend on a paragraph’s purpose. Read the full sentence before choosing a grammatical form and the surrounding ideas before choosing a transition or sentence placement. A detail about a bridge’s repairs belongs in a repair explanation; an unrelated name coincidence usually does not.
Repair the underlying structure
Identify clauses and modifiers rather than guessing where a pause sounds natural. Two independent clauses may be joined by a comma and a coordinating conjunction or by a semicolon. A modifier at the start should describe the following subject. Phrases such as along with two assistants do not turn a singular main subject into a plural subject.
Prefer precise, purposeful expression
Choose a verb that accurately describes the action, and remove duplicated meanings. Maintain consistent person and tone unless context requires a deliberate change. For comparisons, compare like things: this year’s harvest with last year’s harvest. For process paragraphs, place a new sentence at the point where its action occurs. Labeling samples belongs after collecting them and before analyzing them when that is the stated sequence.
- Punctuating only by pauses instead of sentence structure.
- Changing point of view without a reason.
- Comparing a thing with a time period or person instead of a comparable thing.
- Adding an interesting detail that does not support the paragraph purpose.

Frequently asked questions
What makes a detail relevant?
It directly supports the topic of the paragraph, purpose, or claim rather than merely sharing a word with it.
Why can a shorter option be wrong?
It may remove necessary meaning, create a fragment, or change the intended relationship.
How do I place a process sentence?
Identify what must happen immediately before and after its action, then preserve that sequence.
What controls subject-verb agreement?
The grammatical subject, not necessarily the nearest noun.
