1. Verb: When "live" is used as a verb, it describes an action (to exist, to reside, to perform). In this case, it's not a noun at all.
* Example: "We live in a small town."
2. Adjective: "Live" can also be used as an adjective, meaning "alive," "not recorded," or "happening in real-time." It's still not a noun.
* Example: "They have a live band playing tonight."
3. Noun: Less commonly, "live" can be a noun, but only in specific contexts.
* "The live" can refer to a live performance or broadcast.
* Example: "Did you see the live of the concert?"
* In very specific contexts, "live" might refer to a person or animal that is alive.
* Example: "The live was captured for study." (This is very unusual and formal)
In most cases, "live" is a verb or an adjective, not a common noun.
