What word has the most different meanings?

This is a fun question! It's difficult to definitively say which word has the *most* different meanings, as it depends on how you define "meaning" and how you count them.

However, some words are notorious for their versatility:

* "Run": This word can be a verb (to move quickly on foot), a noun (a period of activity), an adjective (relating to running), or a part of a compound word (e.g., "rundown").

* "Set": Similar to "run", "set" has various uses as a verb, noun, adjective, and even a part of phrasal verbs.

* "Get": This word is extremely flexible, acting as a verb in countless ways, as well as a noun and even an interjection ("Get out!").

* "Go": Another versatile word, "go" functions as a verb, noun, adjective, and even an exclamation.

Ultimately, the answer might be subjective. But these words are excellent examples of how language can be remarkably flexible and adaptable.
