Use of Either or and Neither nor
When we have to emphasize a choice, we use the words Either and Or. In simple words, when we have or we give an option to choose between the two possible things or situations, either and or are used.
You can either eat what is cooked or starve for the whole day.
Ria had an option to either stay at home or go to Vegas with her parents.
In most of the situations, either is omitted and only Or is used. For an instance the above sentences can also be written as:
You can eat what is cooked or starve the whole day.
Ria had an option to stay at home or go to Vegas with her parents.
Neither/nor are the negative counterparts of either/or. When we have to emphasize that none of the options is valid we use neither/Nor.
She neither lied to me nor speaks the truth.
Neither blue nor white colour was available in my size.
Unlike either, neither can't be omitted. Neither and nor are used in a pair.
