Now this never really bothered me in the past but on hindsight I stick this thing in my mouth just like food so it would be good to know what its composed of. What really got me though is seeing toothbrushes that say whitening or antimicrobial which begs the question. Why is this whitening or antimicrobial? What the heck is in it that is doing this action??? Now that I think of it this might be more than mildly infuriating.
‘Begging the question’ means using circular logic, not that something makes one curious. An example of begging the question would be asking a heterosexual if their mother knows they’re gay. Hope this helps.
While you’re actually correct, language has moved on and now the meaning of ‘prompts the question’ is the dominant usage by far.
