Yes, you can end a sentence with ‘are’, although it might not be a common practice. The key lies in how the sentence is structured and the context in which it is used.
For example, in a conversational context or in informal writing, you might encounter sentences like:
“These are the shoes I wanted, but where are?”
In this case, the speaker is asking a rhetorical question, and it naturally leads the sentence to end with ‘are’.
Moreover, in poetry or creative writing, breaking grammatical conventions like this can evoke emotion or provoke thought, making it a stylistic choice rather than a rigid rule. Overall, while it’s generally advisable to follow standard grammatical norms in formal writing, casual or creative contexts offer more flexibility.
