Ludwig's WRAP-UP

In summary, "what sure does" is a versatile English phrase most frequently employed in high-quality journalism and academic discourse. Ludwig AI confirms that it is correct and usable, particularly when serving to emphasize agreement or clarify the function of an object. While it often appears within the negative construction "not sure what...", its use as an intensifier is a valid way to add weight to a statement. Writers should be careful not to confuse it with the interrogative word order in indirect questions, but otherwise, it remains a reliable tool for expressing varying degrees of certainty and functional description across different registers.
