Ellipsis and substitution (advanced)
C1 AdvancedEllipsis and substitution streamline communication by omitting redundant words or replacing them with shorter functional terms. These advanced structures maintain cohesion in complex discourse while avoiding repetitive phrasing.
Overview
Ellipsis involves the deliberate omission of words that are recoverable from the context, such as leaving out the main verb after an auxiliary. Substitution replaces a specific word or clause with a pro-form like so, do, or one to maintain flow without repetition.
Common Structures
Subject + auxiliary (ellipsis) / if + not (substitution)
Advanced ellipsis often occurs in conditional clauses and comparative structures. Substitution frequently utilizes auxiliary verbs to represent entire predicates or the word so to represent an entire reported clause.
Examples
Common mistakes
I hope so that he wins.
I hope so.
The substitute 'so' replaces the entire 'that' clause; including both is redundant.
If you want to go, you should to.
If you want to go, you should.
Ellipsis after modal verbs does not require the infinitive marker 'to'.
So vs. Not in Substitution
Note that hope and fear only use not for negative substitution, whereas think and believe can use negative transfer with so.
| Verb Type | Affirmative Substitution | Negative Substitution |
|---|---|---|
| Verbs of opinion (think, believe) | I think so. | I don't think so. / I think not. |
| Verbs of hope/fear (hope, fear) | I hope so. | I hope not. (NOT: I don't hope so) |
Practice
Complete the sentence: 'Will it rain this afternoon?' 'I certainly hope ____.'
Show answer
not
Answer:not
Why:The verb 'hope' uses 'not' as a negative substitute for a clause; 'I don't hope so' is ungrammatical.
Rewrite using ellipsis: 'He said he would finish the project, and he has finished the project.'
Show answer
He said he would finish the project, and he has.
Answer:He said he would finish the project, and he has.
Why:The main verb and object can be omitted after the auxiliary 'has' because they are previously mentioned.
Identify the error: 'If you haven't finished the report, please do so it by tomorrow.'
Show answer
please do so by tomorrow
Answer:please do so by tomorrow
Why:'Do so' acts as a substitute for the entire verb phrase 'finish the report'; adding 'it' is redundant.
