Please find a word that it is not grammatically correct to begin a sentence or question? [closed]

Multiple questions herein ask "Is it grammatically correct to begin a sentence or question with X?"

So, I'm definitively asking, are there any words for which it is absolutely not grammatically correct to begin a sentence with?

I am not looking for a list, and I'm not (effectively) looking for a class of words, though that may be evident if a specific word is presented, but only as a part of

_____ is an example, and words like _____.

I am not looking for discussion, either. I would assume the answer is No, you may grammatically start a sentence with any word. but would like to be proven incorrect.

Than any other question, this one should actually have an answer.

Also, no quotation mark tricks or the like. The word should have grammatical context and retain its own definition in place. Filling in the example also does not count for the answer. (Use, not mention).

The word should itself be grammatically acceptable. If ain't is not grammatically acceptable, then it ain't allowed as a word in this context.


Solution 1:

Yore.

Yore means of long ago, or former times, but it seems only ever to be used in the phrase In days of yore. Are there any other uses of this word?

Edit

Come to that, it would be hard to begin a sentence with Ago.

Solution 2:

The word:

  • galore

... is, so far as I know only used post-positively. This is to say, it always follows the noun it's modifying.

  • There was whisky galore.

I suppose other words such as this (I once heard a linguist describe it as a post-positive determiner!), which only post-modify nouns, would would be well-nigh impossible to start a sentence with. One such example would be the word aplenty. Here's an ungrammatical example for you:

  • *Aplenty were the treats. (ungrammatical)

Of course it is trivially true that any word can be cited at the beginning of a sentence:

  • "Aplenty" is a difficult word to start a sentence with.

But, as I said this is not important to the OP's question!
