Best practice
When indicating necessity or obligation, use "must be" followed by an adjective or a past participle to form a grammatically correct sentence. For example, "The report must be submitted by Friday" or "The door must be locked at night."
Common error
Avoid using "must being" as it combines a modal verb with an incorrect form of the verb "to be". Instead, use the correct form "must be" to express obligation, deduction, or certainty. For example, instead of "The problem must being addressed", say "The problem "must be addressed"".

FAQs
What's grammatically wrong with the phrase "must being"?
The phrase "must being" incorrectly combines the modal verb "must" with the gerund "being". The correct form to use after "must" to express a state of existence or a characteristic is "must be".
When can I use "being" in a sentence?
"Being" can be used as a gerund (a verb acting as a noun), as part of a continuous verb tense (e.g., "is being"), or as a participle modifying a noun. However, it does not directly follow "must"; instead, use constructions like "must be".
How can I correctly express obligation or necessity using "must"?
To express obligation or necessity, use "must" followed by the base form of the verb (e.g., "You "must go""). To describe a state or characteristic, use "must be" followed by an adjective or noun (e.g., "It "must be true"").
