Is "neither I" grammatically correct?

I'm just trying to figure out if "neither I" is grammatically correct as a standalone statment (in spoken English).

Solution 1:

No, it is grammatically unacceptable.

Correct constructions using neither include:

• Neither a nor b: This is the most common usage.

  Neither Alaska nor Florida charges state income tax.

• Neither noun: You can use this variant when it's clear what you are referring to.

  I moved from Alaska to Florida this year. Fortunately, neither state charges income tax.

• Me neither: This may be close to what you had in mind.

  "I don't like Brussels sprouts."

  "Me neither."

• Neither: This could be a one-word sentence.

  "Do you prefer carrots or broccoli?"

  "Neither."
