Grammar Usage of 'At'

The preposition at is used in this sentence. The preposition at, like by, from, or with, connects words in a phrase. However, its role is more versatile than it appears, depending on where it appears in a sentence and which words it connects.

The Preposition ‘At’

A preposition is a "connector" word that can clarify the location, time, or relationship of a phrase while also linking the words together. The preposition at denotes a certain location, time, or position.

Consider the following example:

• Joe is at home, ready to go. (where is Joe waiting?)

• The appointment is at 9 P.M. (when is the appointment — what time is it?)

• The progress bar is at 75%. (where is the progress metre?)

The preposition at alters the sentence's topic (Joe, the appointment, the progress meter). At is always followed by a noun, which is referred to as the preposition's object.

Sentences with the word "at" in them

Here are a few more examples to consider. Keep the above-mentioned principles in mind as you play. First, at serves as a connector, connecting the subject/verb with the direct object. Second, a noun or pronoun, most likely the direct object, is followed by at.

1. I cried while I sat at my table. Let's meet at 11:45 a.m. (my table is the subject of the preposition).
2. The car will come to a complete stop at the curb.
