The best questions often start with “wait, so...” That’s your brain catching a gap in real time.

That half-formed interruption is the sound of two things you believe failing to fit together. It arrives before you can phrase it properly, which is why it comes out clumsily, and the clumsiness is a sign it is real rather than rehearsed. A gap you catch while it is open is far easier to close than one you meet again during revision.

Say it when it happens, even unfinished. Let the sentence trail off and let somebody help you finish it. If you are on your own, write the fragment in the margin and come back to it tonight.
