no. if a sentence was going to end with "neither" it has to be changed to "either" however it can be used as if for example someone is a writer and someone is asking them about the words they put in the story. they could say " did you use the word neither" in that case i think the correct answer to your question is yes. a sentence can end in the word neither
Neither of the books you are looking for are available
"Neither is Grandma" is a sentence because it includes a subject and a verb pertaining to the subject (the subject does it). "Neither is Grandma" can be rewritten as "Grandma is neither", which is more obviously a sentence, though we would not normally say it that way.
"Nor" typically pairs with "neither" to form a correlative conjunction. For example, "She wanted neither the red dress nor the blue dress."
neither tom or Jim went to the park.
I don't like sushi, neither does my friend.
A declarative sentence is ended with a period.
ended
Neither the cat nor the dog wanted to go outside in the rain.
You put a period at the end of the sentence to indicate that the sentence has ended.
An example of using nor in a sentence would be: " They had neither fish nor cheese at the party." It usually has to be paired with neither to work properly in a sentence. Nor goes with neither. Or goes with either. The color, gray, is neither black nor white. I prefer either gray or black for lettering.
Neither you or I will be able to go.Our vacation will be neither Paris or Palm Beach, it will be right here in Passaic.
It means the sentence is punctually ended.
