Definition of the word <b>must</b>

Origin of the word must

The word "must" has a rich history! It originated from Old English and Germanic languages around the 9th century. The Proto-Germanic word *mussiz, meaning "necessity" or "compulsion," evolved into Old English as "mōst" or "mōste". This indicated obligation, requirement, or being forced to do something. In Middle English (circa 1100-1500), "must" further developed to express necessity, necessity of the future, or obligation. For example, "thou must go" meant "you are obliged to go". Over time, the verb "must" has taken on various connotations, encompassing not only obligation but also inevitability, necessity, and sometimes even a sense of force or coercion. Now, "must" is a fundamental part of the English language, used in a wide range of contexts to convey meaning, intention, and direction. Whether expressing obligation, necessity, or simply conveying a sense of "you have to", the word "must" continues to play a significant role in our daily communication.
