Neither- nor

“Neither” is a singular adjective and can be paired with “nor”. When using neither-nor, you are saying that not the first object and not the second object are behaving in a certain way.

Example:

-Neither Larry nor Suze went to the beach. (Larry didn't go to the beach, Suze didn't go to the beach)

- For some people, going to the local library is neither interesting nor enjoyable. (going to the local library is not interesting and not enjoyable)

X: I don't like broccoli

Y: Neither do I (means: “I don't like broccoli too”. You may hear some people say “Me neither,” this is colloquial and not grammatically correct. You wouldn't say “Me don't like broccoli”)

Usually, either-or and neither-nor are used for mentioning two items, but sometimes they appear with three items.

- Neither snow, nor rain, nor heat can stop me.

An older form for this correlative was nor-nor:

- Nor sun nor wind will ever strive to kiss you. (Shakespeare)

You can use “nor” independently. Examples:

- She will not go to university, nor will she look for a job.

- I have never seen him since then, nor do I expect to see him again.

- I didn't murder anybody, nor will I.

Take a look to the examples above, auxiliary verbs are placed before the subjects. Therefore, you wouldn't say “I will not go to the dentist, nor I will go shopping.” Instead, say “I will not go to the dentist, nor will I go shopping.”

Sometimes instead of “neither”, a negative form may function with the first item. In such case, “or” or “nor” may appear with the last item.

- Bella owns no money (n)or jewelry.

Using “never”, “seldom”, or “rarely” in the first clause:

- He has never (or “seldom”, “rarely”) spoken a bad word to his wife (n)or to anyone else.

The use of “nor” in the sentences above reinforces the negation.

Either- or

Either means “one or the other, but not both”.

- She wanted to eat either spaghetti or steak. (She wanted to eat spaghetti or steak, but not both)

- I can't remember if either Fred or George stole a car. (One of the boys stole a car, but not both)

Whether-or is sometimes used instead of either-or.

- Whether out of avarice or out of need, he asked for a much higher price for his property than it was worth.

If two singular subjects are connected by neither-nor or either-or, match the verb with whichever subject it's closer to.

- Neither Olive nor the boys eat mushrooms.

- Neither the boys nor Olive eats mushrooms.

- Either one rat or several mice are eating everything in the cupboard.

- Either several mice or one rat is eating everything in the cupboard.

Critical Age Hypothesis

Children under 12 years old will be able to learn any languages like the native speakers. When an American family lives in France, for instance, then they have a baby who then socializes with his French friends until, say, 7 years old, he will be able to speak French like a native speaker. This happens because in children under 12 years old, there is no lateralization. That is, the two hemispheres are not “separated” yet to be given their own function. They both are flexible, they can accept any commands. That is why patient with stroke under 12 can get 100% recovered in acquiring language, while adults just have little chance to get 100% recovered.

After 12, lateralization process begins. The brain will not be as flexible as before. Ability to speak like a native will decrease. That is why an adult learning foreign language will almost sound like a foreigner, even though he stays for a long time in the country where the language is used in everyday life. He may master the grammar rules, but still his accent will sound like a foreigner.
