Rule	Base / Standard Form	Applied Form
Clarity Maintenance Rule	Ellipsis is ONLY valid if the omitted words can be 100% reconstructed from immediate context without ambiguity!	I can swim and Mary can too
Subjunctive/Auxiliary Retention	Always retain the auxiliary verb or infinitive particle "to" to anchor the omitted predicate.	I'd love to. / Yes, I can.
Formal vs Informal Scope	Conversational front-dropping ([Have you] seen him?) is informal. Parallel ellipsis (singing and dancing) is required in all formal writing.	singing and dancing

❓ Frequently Asked Questions (FAQ)

Q1: What is the grammatical difference between Ellipsis and Substitution?

Ellipsis OMITS words completely ("I want to go, but I can't [go]"). Substitution REPLACES words with placeholders like "one", "so", or "do" ("Do you think so?").

Q2: Can we omit the verb BE after "if" or "when"?

Yes! In adverb clauses: "When [it is] necessary, call me" or "If [it is] possible, let me know."

Q3: Why is ellipsis important for C1 level proficiency?

Because native English speakers rely heavily on ellipsis for natural speech rhythm and concise writing. Over-repeating words is a hallmark of lower-level learners.
