When is strange used as a noun?

"Strange" is rarely used as a noun in standard English. It is almost always used as an adjective, meaning "unusual, unfamiliar, or odd."

However, in some informal or dialectal contexts, "strange" can be used as a noun, meaning:

* A strange or unusual person or thing: "He's a real strange."

* An odd or peculiar situation: "There's a strange going on in the neighborhood."

It's important to note that these uses are not considered standard English and are likely to be understood only by speakers familiar with the specific dialect or context.

In most cases, if you want to use "strange" to refer to a person, thing, or situation, you should use a more formal noun, such as:

* Stranger: A person you don't know.

* Oddity: Something unusual or peculiar.

* Mystery: Something that is unexplained or puzzling.

* Anomaly: Something that deviates from what is standard or expected.
