However, there are times when starting a sentence with "because" can be grammatically correct, even if it's not always considered the most elegant choice. For example, in a sentence like "Because of the rain, the game was cancelled," the "because" phrase is functioning as an adverbial phrase, providing the reason for the cancelled game.
It's important to note that the use of "because" at the start of a sentence can sometimes sound awkward or informal, especially in formal writing.
