Does a sentence start with or?

Could you please clarify your question, as it seems a bit unconventional to ask if a sentence starts with "or"? Typically, sentences do not begin with conjunctions like "or" unless they are part of a larger construction, such as a compound sentence or a question. However, if you're asking about the grammatical correctness of starting a sentence with "or" in a specific context, it would depend on the sentence structure and the intended meaning. For example, in a list of options, it's common to use "or" to separate items, but the sentence as a whole would not technically start with "or." Could you provide more context or clarify your question?
