No. Ending is a verb form, or a noun, and may be an adjunct (e.g. ending credits). It can create a participial phrase, but it is not a preposition.
No--at is a preposition, and you technically shouldn't end a sentence with a preposition. In this example, it is sufficient to say "Where do you live?"
This would depend on who you ask. In most schools, a teacher would tell you NOT to end a sentence with 'since' because it is a preposition. However, it is perfectly acceptable to end a sentence with a preposition, such as 'since', if the alternative would create confusion. With this being said, you should stay away of doing this and find a better alternative.
No. There is a slang usage, as in "That's not where I'm at," meaning it does not describe my attitude or motives accurately, but speaking of location, where plus at is simply not standard English.
preposition
Before is a preposition, so it's grammatically incorrect to use it as the last word in a sentence.
It stars with a preposition and ends with a noun
According to proper English grammar, no. "With" is a preposition. You aren't supposed to end a sentence with a preposition.
The noun or pronoun at the end of a prepositional phrase is the object of the preposition.
It has always been proper to end an English sentence with a preposition. The utterly false rule about not ending a sentence with a preposition comes from an ill-starred attempt to make English conform to the rules of Latin grammar, where a sentence may not end with a preposition. English is not Latin: we can end a sentence with a preposition IF WE WANT TO. Winston Churchill said that the Victorian grammarians' diktat that a sentence must not end with a preposition " . . . is a restriction up with which I will not put".
You are referring to the object of the preposition. In "under the sink," "sink" is the object of the preposition.
The preposition at is used before an object of the preposition in a sentence. It should not be used at the end of a sentence. Examples: "I was at the store." - Correct (store is the object of the preposition.) "Prepositions should not be used at the end of a sentence." - Correct (end is the object of the preposition that goes with at.) "Where is my phone at?" - Incorrect Instead, one would say, "Where is my phone?"
A prepositional phrase begins with a preposition and ends with a noun or pronoun, known as the object of the preposition.
The word at the end of a prepositional phrase is called the object of the preposition. It is the noun or pronoun that the preposition acts upon in the sentence.
Never end a sentence with a preposition.
In English, it is generally acceptable to end a sentence with a preposition, especially in spoken language. However, in formal writing, it is often preferred to rephrase the sentence to avoid ending it with a preposition. Adverbs can also appear at the end of a sentence to modify a verb or adjective.
What are you talking about? A preposition is the worst thing in the world to end a sentence with. This is unheard of. This is a habit that you should stay far away from. Rearranging the sentence to remove the preposition from the end of the sentence is the rule that you should abide by.(Hopefully, you have picked up on the sarcasm by this time. Each sentence in the above paragraph ends with a preposition, and all are grammatically correct. There is no rule, at least in the English language, that forbids ending a sentence with a preposition, whether written or spoken, formal or informal.)
It is generally considered acceptable to end a sentence with a preposition in informal settings, but in formal writing, it is recommended to rephrase the sentence to avoid ending with a preposition.
