Ellipsis and substitution in English C2
Remove recoverable material or replace it with one, ones, do so, so and not while preserving reference, contrast and register.
Distinguish ellipsis from substitution.
Recover omitted material without losing reference.
Choose natural devices for conversation, formal prose and comparison.
Ellipsis and substitution are different operations
In Maya can sing and Leo can too, the repeated verb phrase is omitted after can: this is ellipsis. In I need a pen; do you have one?, one replaces the noun phrase: this is substitution.
Both create cohesion, but they obey different structural restrictions.
Recoverability is the central test
A listener must be able to reconstruct the intended material from the grammar and discourse. If two possible antecedents compete, the shorter version becomes ambiguous rather than elegant.
Parallel structure, agreement and contrast all help the reader recover what is absent.
| Question | Check |
|---|---|
| What is missing? | identify the repeated constituent |
| Where is its antecedent? | locate the recoverable source |
| Could another reading fit? | remove ambiguity |
Choosing among one, do so and so
One and ones substitute for count noun phrases. Do so replaces a verb phrase, especially in planned or formal prose. So and not substitute for whole propositions after verbs such as think, hope, suppose and expect.
Lexical choice and register matter: She said she would and She undertook to do so are both cohesive, but they belong to different contexts.
Natural economy, not mechanical deletion
Not every repetition is a flaw. Repeating a key noun can protect clarity across a long paragraph, and full wording can carry emphasis that ellipsis would remove.
Use economy where the relationship remains immediate and unmistakable.
