How do you say either/neither?

[biglittleproblems]

(Ee)ther or (I)ther
(Nee)ther or (Ni)ther

Like this.

All four, and I'm trying to work out if there's any rhyme of reason of how I'm choosing.

It think with neether or neiither, the former is if I'm quite chill about the situation -( "Would you rather have chocolate or caramel ice-cream?" "'Neether, I'd prefer vanilla") and the the latter if I'm outraged by either suggest ("Would you rather that I shave your left or right eyebrow off in your sleep" "Neiither - don't even think about it")

Mainly eye / nye .

I use all 4.

I think I mainly use eether and nyether. But the other options thrown in occasionally.
