Sentence structureC1

Ellipsis and substitution: so, neither, do so

Not repeating yourself: short agreements (So do I / Neither can she), do so, one/ones, and if so/if not

Learning Goal

I can agree, disagree and avoid repetition with the so/neither/do so toolkit.

Look at these examples. Can you spot the grammar pattern?

I can't stand laugh tracks. — Neither can I, and nor can my dad.

I can't stand laugh tracks. — Neither can I, and nor can my dad.

Asked to apologize publicly, the minister declined to do so.

Asked to apologize publicly, the minister declined to do so.

Pay attention to the highlighted parts. What do they have in common?

English hates repetition — the toolkit:

ToolExample
So + aux + subjectI love jazz. — So do I.
Neither/Nor + aux + subjectShe can't ski. — Neither can I.
do soAsked to resign, he refused to do so.
one / onesWhich cake? — The lemon one.
if so / if notFree tonight? If so, join us.

Polarity check: agree with negatives via Neither, not *So don't I.
