Leaving Words Out: Ellipsis

I can leave recoverable material unspoken without changing tense, polarity or reference.

Created by , British English teacher.

I’m studying:

Try the activities, then check your answers.

Choose a short recording.

Start with the contrast

“Will Sam attend?” “I hope so.” “I can stay late.” “So can I.” “I haven’t seen the draft.” “Neither have I.” These brief replies do different jobs: substituting for a proposition, expressing positive agreement and expressing negative agreement. Their brevity depends on a clear earlier message.

“Will Sam attend?” “I hope so.” “I can stay late.” “So can I.” “I haven’t seen the draft.” “Neither have I.” These brief replies do different jobs: substituting for a proposition, expressing positive agreement and expressing negative agreement. Their brevity depends on a clear earlier message.

In “Neither have I”, what must match the earlier statement?

Compare your idea

Its negative orientation and the auxiliary have; the reply means I haven’t seen the draft either.

How it works

Two adults have a concise conversation over a closed draft folder.
“I’ve read the draft.” “So have I.”Picture context: both adults have read the draft in the folder. Have matches the present-perfect statement.

Use the appropriate auxiliary when repeated verb material is omitted: she can, I haven’t, they did. Match tense and polarity to the intended message, not merely the nearest word.

So + auxiliary + subject commonly expresses positive agreement; neither + auxiliary + subject expresses negative agreement. I think so substitutes for a proposition. These replies require clear reference; if two earlier claims compete, a fuller answer may be clearer.

Agreement: so/neither + auxiliary + subject. Verb ellipsis: subject + auxiliary. Proposition substitute: think/hope + so where licensed.

Notice this

I can stay late. So can I.

The second speaker can stay late too.

Compare this

I haven’t seen the draft. Neither have I.

The second speaker has not seen it either.

Hear the examples

I can stay late. So can I.

The second speaker can stay late too.

I haven’t seen the draft. Neither have I.

The second speaker has not seen it either.

Will Sam attend? I hope so.

So refers to Sam attending.

Jo called, but Lee didn’t.

Didn’t stands for did not call.

One mistake worth avoiding

Instead of: I haven’t seen it. Neither did I.

Say: I haven’t seen it. Neither have I.

Use have to match the present-perfect negative statement in this exchange.

You say

Hear the prompt, answer aloud, then deliberately reveal or hear one possible model. Check it and retry with a changed detail.

Your turn 1

Agree with a positive ability statement.

Compare a possible model
Reveal the model text

I can stay late. So can I.

Check yourself: Keep the modal can.

Retry with one detail of your own. Other wording is welcome when it meets this check.

Your turn 2

Agree with a negative present-perfect statement.

Compare a possible model
Reveal the model text

I haven’t seen the draft. Neither have I.

Check yourself: Keep both negative agreement and have.

Retry with one detail of your own. Other wording is welcome when it meets this check.

Your turn 3

Make a short reply, then expand it to prove the reference is clear.

Compare a possible model
Reveal the model text

Will Sam attend? I hope so: I hope Sam will attend.

Check yourself: Check what the substitute represents.

Retry with one detail of your own. Other wording is welcome when it meets this check.

Two adults have a concise conversation over a closed draft folder.
“Will they accept the draft?” “I think so.”Picture context: they discuss whether the draft will be accepted. So substitutes for that proposition, not an action.

Two guided self-checks

Say or write your answer before opening a model.

Self-check 1

Expand: “Jo called, but Lee didn’t.”

Compare a model and explanation

Jo called, but Lee did not call.

The auxiliary carries the negative past meaning.

Self-check 2

Respond with negative agreement to “I can’t stay.”

Compare a model and explanation

Neither can I.

The modal can remains after neither.

Check your understanding

Choose one answer to each question, then check your answers. One of the ten questions is listening.

1. “I can stay.” “So ___ I.”

2. “I haven’t seen it.” “Neither ___ I.”

3. In “Will Sam attend? I hope so”, so refers to ___.

4. Which reply gives negative agreement to “I can’t stay”?

5. Expand “Lee didn’t” after “Jo called”.

6. Correct the auxiliary in “I haven’t read it. Neither did I.”

7. What can make a very short reply unclear?

8. Has the second speaker seen the draft?

Read the listening transcript

I haven’t seen the draft. Neither have I.

Opening this transcript makes this a reading-supported attempt.

9. Which response explicitly resolves an ambiguous reference?

10. What makes omission successful?

Automatic scoring needs JavaScript. Use the answer key after attempting all ten questions.

Answer key with explanations
  1. “I can stay.” “So ___ I.”

    can: The reply matches the modal can.

  2. “I haven’t seen it.” “Neither ___ I.”

    have: Negative agreement preserves the present-perfect auxiliary have.

  3. In “Will Sam attend? I hope so”, so refers to ___.

    Sam attending: So substitutes for the proposition in the question.

  4. Which reply gives negative agreement to “I can’t stay”?

    Neither can I.: Neither can I means I cannot stay either.

  5. Expand “Lee didn’t” after “Jo called”.

    Lee did not call.: Didn’t preserves the past-simple negative.

  6. Correct the auxiliary in “I haven’t read it. Neither did I.”

    I haven’t read it. Neither have I.: The response matches have in the present-perfect statement.

  7. What can make a very short reply unclear?

    Two competing propositions in the previous turn: Ellipsis relies on recoverable context; competing antecedents can obscure the meaning.

  8. Has the second speaker seen the draft?

    No: Neither have I expresses the same negative situation for the second speaker.

  9. Which response explicitly resolves an ambiguous reference?

    I hope Sam attends; I’m not commenting on the budget.: The fuller response names the intended proposition.

  10. What makes omission successful?

    The listener can recover the intended content, tense and polarity.: Brevity must preserve meaning and a clear connection to the earlier turn.

Take it with you

I can leave recoverable material unspoken without changing tense, polarity or reference.
