The query is a sequence of words each on a new line: "is this sentence grammatically correct". This is not a fully formed sentence because it lacks proper structure and punctuation as a single unit. To be grammatically correct, the question should be written as a single sentence: "Is this sentence grammatically correct?" with a capital letter at the beginning and a question mark at the end. Hence, the original formatting of the query as separate words on separate lines is not grammatically correct. The correct form is a properly capitalized and punctuated sentence. This aligns with standard grammar rules that a question must be a complete, structured sentence with appropriate punctuation.
