Agreeing in echo: So do I / So am I / So can she; Neither do I for negatives; the auxiliary must match
I can echo agreement with the matching auxiliary in so/neither patterns.
Look at these examples. Can you spot the grammar pattern?
I've never tried surfing. - Neither have I, but the lessons start Monday.
I've never tried surfing. - Neither have I, but the lessons start Monday.
She's allergic to cats. - So is her cat, ironically.
She's allergic to cats. - So is her cat, ironically.
Pay attention to the highlighted parts. What do they have in common?
Pick the matching auxiliary:
| Statement | Me too | Me neither |
|---|---|---|
| I love jazz. | So do I. | - |
| I'm tired. | So am I. | - |
| I can't swim. | - | Neither can I. |
| I've seen it. | So have I. | - |
Pattern: So/Neither + auxiliary + subject (inverted!). The auxiliary copies the original: be→be, modal→modal, plain verb→do/does/did. Casual shortcuts: Me too / Me neither. Disagreeing: Oh, I don't. / Really? I do.
