ACT English Ellipsis: Understand When Words Can Be Omitted for Parallelism

Ellipsis is omitting a word that's understood from context to maintain parallel structure. Example: "John likes swimming, and Mary likes running" can become "John likes swimming, and Mary running" (likes is omitted but understood). However, you can only omit a word if it applies the same way to both parts. Example: "She can solve the problem and complete the assignment" can become "She can solve the problem and complete the assignment" (no omission needed for clarity) or "She can solve and complete the problem and assignment" (can applies to both verbs; problem applies to both). Ellipsis works when the omitted word has the same function and meaning in both parallel parts.

Invalid ellipsis: "She will go to Paris and to marry someone there." (will applies differently: will go vs. will marry someone there). Fix: "She will go to Paris and marry someone there" or "She will go to Paris and will marry someone there."

Mistake 1: Omitting a word when it has different meanings or functions in the parallel parts. "She is an author and writes books" works without omission, but "She writes books and author" doesn't (writes and author don't parallel). Mistake 2: Creating confusion by omitting a word that's necessary for clarity. "He likes coffee and John" (should be "He likes coffee, and John likes tea" because what John likes is unclear). Mistake 3: Breaking parallel structure while trying to use ellipsis. Ellipsis must maintain parallelism; if removing a word breaks the structure, keep the word.

During practice, test ellipsis by reading the sentence with the word omitted. Does it still make sense and maintain parallel structure? If not, keep the word.

Sentence 1: "She studies French and Spanish languages." Correct (languages understood for both). Sentence 2: "He will go to Paris and marry someone." Correct (will applies to both; ellipsis of will go understood). Sentence 3: "The team practices hard and the coach demands excellence." Might need revision for parallel structure; not necessarily ellipsis. Sentence 4: "She writes novels and her brother writes poetry." Could use ellipsis: "She writes novels and her brother poetry" (writes understood). Sentence 5: "The food was delicious and the service." Incorrect (service delicious doesn't work). Should be: "The food was delicious and the service was attentive." Evaluate whether ellipsis works or if words should be included.

Find five ellipsis/parallelism questions from a practice test. For each, test whether omitting a word maintains sense and parallelism. By the fifth question, ellipsis judgment will be clearer.

Ellipsis questions appear occasionally on ACT English and test nuanced understanding of parallel structure. Students who master ellipsis judgment pick up 1 point because they understand when omission maintains clarity and when it creates confusion.

Review ellipsis rules this week. On every practice test, mark sentences with potential ellipsis and test whether the omission works. By test day, you should evaluate ellipsis confidently.
