Building the Teirutz: The Basic Structure
In every sugya, after the Gemara presents a kushya, it strives to resolve it. The teirutz is the solution, the resolution, the answer to the objection raised. It rebuilds understanding.
אלא מאי אית לך למימר... תירוץ!
Rather, what do you have to say... this is the resolution!
A teirutz is not merely an 'answer.' It always comes in response to a problem presented. A kushya and a teirutz are an inseparable pair.
