what's the difference between I don't know and neither do I?

Answer 1

I have know idea

Answer 2

The person speaking has changed at the point when neither do I is said.

The first admits ignorance the second just jumps on the bandwagon

the letters k,n,o,w are exchanged for h,e,i,r other than those they are the same

the latter phrase has ten letters the former, nine

Beats the wholly living daylights out of me!

Answer 3

"What's the answer to this question? Neither do I."

Doesn't make any sense, does it? 'Neither do I' has to follow a statement, not a question.

'Neither do I' just means 'I don't ... either'. You can put any verb where the dots are, not just 'know'. Eg

I don't like spinach.
Neither do I.

I don't use make-up.
Neither do I.

I don't play golf.
Neither do I.

etc etc

Answer 4

"I don't know" is a statement which plainly sets out your knowledge about a subject whereas "and neither do I" is a follow on which agrees with a statement which has been made by someone else.

Basically they both mean the same thing, it just depends upon who made the first statement.

Answer 5

neither do i (but i know the difference between know and no.)

Answer 6

i don't know is definitely acknowledging your ignorance on a matter while neither do I, is sharing unawareness or lack of knowledge on something with another person or persons.

Answer 7

The place in the conversation where they will happen. "I don't know" comes first. "Neither do I" comes second.

Answer 8

well if you don't know and i don't know then i can say " neither do i" but you can't unless it was me who said "i don't know" then you can say "neither do i" simple innit
