With auxiliaries and infinitives, the words you retain show how the understood action relates to tense, modality or negation. The aim is concise expression without unclear reference.\n\n## 1. Leave out a recoverable verb phrase\n\nIn **verb phrase ellipsis**, an auxiliary remains while the following verb phrase is understood. The missing material may include the main verb, its objects and other closely connected information.\n\n:::example\nMaya **has submitted the revised proposal**, but Leo **hasn't**.\n\nHere, **hasn't** means *hasn't submitted the revised proposal*, not simply *hasn't submitted*.\n\nI thought the printer **would work**, but it **didn't**.\n\nHere, **didn't** means *didn't work*. The retained auxiliary expresses the actual past result.\n:::\n\nThe missing material need not be repeated word for word: its grammatical form adapts to the new subject or auxiliary. However, the intended meaning must be clear. If several actions are possible, repeating the main verb is often better than using ellipsis.\n\n## 2. Choose the appropriate auxiliary\n\nRetain an auxiliary that fits the meaning of the new clause. If the understood verb phrase has no auxiliary, use **do, does** or **did**.\n\n| Structure | Full version | With ellipsis |\n| --- | --- | --- |\n| Modal | Nina can attend, and Omar can attend too. | Nina can attend, and Omar **can** too. |\n| Perfect | Nina has replied, but Omar hasn't replied. | Nina has replied, but Omar **hasn't**. |\n| Progressive | Nina is working, but Omar isn't working. | Nina is working, but Omar **isn't**. |\n| Passive | Nina was invited, but Omar wasn't invited. | Nina was invited, but Omar **wasn't**. |\n| Present simple | Nina agrees, but Omar doesn't agree. | Nina agrees, but Omar **doesn't**. |\n| Past simple | Nina objected, and Omar objected too. | Nina objected, and Omar **did** too. |\n\nAgreement and tense belong to the clause containing the ellipsis, not automatically to the earlier clause.\n\n:::example\nShe **works from home**, and I **do** too.\n\nHe **doesn't drive** now, but he **did** before his accident.\n:::\n\nWith **be** as the main verb, retain **be**, not **do**: *I wasn't ready, but Elena **was***. Here, the omitted material is the complement *ready* rather than an action verb phrase.\n\n## 3. Decide how much of an auxiliary chain to retain\n\nWhen a clause contains several auxiliaries, ellipsis can begin at different points. More than one shortened version may therefore be possible.\n\n:::example\n“Has Lena been working late?”\n\n“Yes, she **has**.” → *has been working late*\n\n“Yes, she **has been**.” → *has been working late*\n:::\n\nThe shorter answer leaves more material understood. The longer answer retains the progressive auxiliary **been** and may give that part of the meaning greater emphasis.\n\nDo not remove an auxiliary that is needed to express a new meaning.\n\n:::example\n“Did you send the attachment?”\n\n“No, but I **should have**.” → *should have sent the attachment*\n:::\n\nHere, **have** establishes the past-time reference of the unfulfilled obligation. *I should* would normally suggest a present or future obligation instead.\n\n:::warning\nDo not normally use a contracted affirmative form of **be** or **have** as the final word in these elliptical clauses.\n\n✓ “Are you ready?” “Yes, **I am**.”\n\n✗ “Are you ready?” “Yes, **I'm**.”\n\n✓ “Has she finished?” “Yes, **she has**.”\n\n✗ “Has she finished?” “Yes, **she's**.”\n\nNegative contractions are possible: **I'm not**, **she hasn't**, **they aren't**.\n:::\n\n## 4. Retain infinitival to\n\nAfter a word or expression that takes a **to-infinitive**, you can often retain **to** and omit the following verb phrase. This is common after expressions such as **want to**, **hope to**, **intend to**, **would like to** and **be supposed to**.\n\n:::example\nI haven't read the report yet, but I **intend to**.\n\nYou don't have to attend the reception unless you **want to**.\n\nThey asked me to explain, but I **refused to**.\n:::\n\nFor a negative infinitive, **not to** can remain:\n\n*I was going to complain, but I decided **not to**.*\n\nThis means *decided not to complain*. Compare *I **didn't decide to** complain*, which denies making that decision rather than stating a decision against complaining.\n\n:::note\nThe **to** must be an infinitive marker, not a preposition. You cannot shorten *I'm looking forward to meeting you* to *I'm looking forward to*: this expression needs a complement after the preposition **to**.\n:::\n\n## 5. Keep be or have when the structure needs it\n\nDo not assume that every infinitive must be shortened to **to** alone. Retaining **be** or perfect **have** can preserve an important structural or time distinction.\n\n- **Copular be:** *I'm not a member, but I'd like **to be***. The omitted complement is *a member*.\n- **Passive be:** *She wasn't shortlisted, although she had expected **to be***. The omitted word is *shortlisted*.\n- **Perfect have:** *I haven't finished yet, but by Friday I expect **to have***. The understood phrase is *finished*; **have** presents completion by the future reference point.\n\nThese are different from *I haven't finished yet, but I hope **to***, where **to** stands for the ordinary infinitive *to finish*. Choose the structure for the intended meaning rather than mechanically copying the earlier auxiliary.\n\n## 6. Check reference and emphasis\n\nEllipsis is common in conversation, but it also makes formal writing less repetitive. In speech, a retained auxiliary often receives stress when it marks a contrast: *I thought she wouldn't object, but she **DID***.\n\nBe especially careful with possessives:\n\n:::example\nAnna revised her proposal, and Ben **did** too.\n\nThis can mean that Ben revised **Anna's proposal** or that he revised **his own proposal**. Context may resolve the reference; otherwise, state it explicitly.\n:::\n\nBefore using ellipsis, check:\n\n1. **Recovery:** Is the omitted action or complement identifiable?\n2. **Grammar:** Does the retained auxiliary fit the new subject and tense?\n3. **Meaning:** Have you preserved necessary modality, negation and time reference?\n4. **Clarity:** Could a pronoun or possessive be understood in two ways?\n\nKeep **an auxiliary**, **to**, or **to be \u002F to have** as the structure requires. Repeat the missing words whenever brevity would make the meaning uncertain.","en","C1",97.01,[13],{"id":14,"name":15,"level":10,"language":9,"isCompleted":16,"completionPercentage":17,"totalExercises":18,"completedExercises":17},"01a0e1ab-d505-7ccd-a097-30c80f838585","Ellipsis and substitution",false,0,8,"2026-09-27T07:02:10+00:00","2026-10-14T10:40:29+00:00",[],{"name":15,"slug":23,"language":9},"ellipsis-and-substitution-c1",[],[26,37,46,55],{"@id":27,"@type":28,"id":29,"grammarPage":30,"title":31,"instructions":32,"displayOrder":17,"type":33,"questionCount":34,"blankCount":35,"isCompleted":16,"ogImageUrl":36},"\u002Fapi\u002Fgrammar_exercises\u002F01a0e1ab-d940-77f1-9590-a2c100e26f2a","GrammarExercise","01a0e1ab-d940-77f1-9590-a2c100e26f2a","\u002Fapi\u002Fgrammar_pages\u002F01a0e1ab-d5aa-756b-b06b-76ca59800cb2","Ellipsis with Auxiliaries and Infinitives — Forms in Context","Choose the option that completes each sentence in context.
