Inversion for Emphasis

Fronting a negative word flips subject and verb

Hindi achieves emphasis by moving a word to an unusual position in its relatively free word order, or by attaching an emphatic particle like ही ('only/precisely') or भी, without needing to physically swap the subject and the verb — Hindi verbs don't carry the do-support English relies on, so there's nothing to invert. English inversion is more mechanical: certain negative or restrictive words (never, rarely, seldom, not only), when placed at the very front of a sentence for dramatic effect, force question-style word order in what's still a statement — have and I trade places, exactly as they would in a real question. This is a formal, literary register — reserve it for writing or a deliberately emphatic tone, not everyday conversation.
