Only in one context, which is seen in the question: you used "the" as a noun exemplar of "the word" and the object of analysis, and not as a grammatical component of the sentence. When used as an article, "the" cannot appear at the end of a sentence.
Yes, "He poured water into the glass." is a grammatically correct sentence as long as the first word is capitalized and there is a period at the end.
Before is a preposition, so it's grammatically incorrect to use it as the last word in a sentence.
From a technical grammar standpoint, the sentence violates no grammar rules. However, the prepositional phrase at the end makes no sense. You can correct the sentence by replacing the word "for" with the word "of" or the word "about."
yes, it is
Yes it is. The sentence "This will be an exciting month for me" is absolutely correct (it needs a period at the end, of course). But "a correct grammar" is not-- you want to ask whether it is "grammatically correct," or to be simpler, ask whether it is "good English."
no
Yes, it is grammatically correct to end a sentence with the word "so." However, it may be informal or conversational in style.
Yes, "He poured water into the glass." is a grammatically correct sentence as long as the first word is capitalized and there is a period at the end.
It depends on the context of what you are writing.
Yes, I can: I didn't get a ride, I got here on my own.
Honda Motors sells cars. correct with a period at the end :)
Before is a preposition, so it's grammatically incorrect to use it as the last word in a sentence.
yes that would be grammatically correct. Some editors, old-fashioned ones perhaps, would change "to all end" to "all to end" on the grounds that the former is a "split infinitive."
Yes, it is grammatically correct to end a sentence with the word "at" in certain cases, such as in informal speech or when emphasizing a location or time. For example, "Where are you going to meet me at?" However, in formal writing, it is generally better to rephrase the sentence to avoid ending with a preposition.
Yes, it is grammatically correct to begin a sentence with a preposition in certain cases, especially in informal or conversational writing. However, it is generally avoided in formal or academic writing.
No. Sentences shouldn't end in prepositions. "Across" is a preposition.
No, it is not grammatically correct because it has a redundancy of words. The correct phrase is, " . . . where are you?" (This one is nearly as bad as " end result", or "fall down", or "rise up".)
