In English, the phrases "in the corner" and "at the corner" are both related to corners, but they are used differently and have different meanings.
First, let's take a look at the meaning of "at the corner". When describing the location of an object, "at" is often used to denote a specific, small-scale location such as a specific corner, intersection, etc. For this reason, "at the corner" is often used to describe the location of a person or object at a specific corner or intersection. For example, "The bus stop is at the corner of main street and elm **enue."(The bus stop is at the intersection of Main Street and Elm**Enue.) ）
"In the corner" has a different meaning. This phrase is often used to describe someone or an object within a certain range of a corner, not just the edge of a corner. It emphasizes that an object or person is enclosed inside a corner, rather than just at the edge of a corner. For example, "the cat was hiding in the corner of the room."(The cat hides in the corner of the room.) ）
Also, the usage of these two phrases is different. When describing a location, "at the corner" is often used to describe a specific, small-scale location, while "in the corner" is often used to describe a larger-scale location or state. For example, "I was standing at the corner when the accident happened."(I was standing at the intersection at the time of the accident.) and "the painting was hanging in the corner of the room."(The painting hangs in the corner of the room.) ）
To sum up, the phrases "in the corner" and "at the corner", although both related to corners, have different usages and meanings. When using it, you need to choose the right phrase according to the specific context to accurately express your meaning.
