Have you read the SEP article Questions? The author addresses two areas of philosophical intersectionality:
After going over some preliminaries we will focus on three lines of work on questions: one located at the intersection of philosophy of language and formal semantics, focusing on the semantics of what Belnap and Steel (1976) call elementary questions; a second located at the intersection of philosophy of language and philosophy of science, focusing on why-questions and the notion of explanation; and a third located at the intersection of philosophy of language and epistemology, focusing on embedded questions.
The TLDR is a question is an utterance that, although not assertoric by nature as it exerts no propositional attitudes towards truth, is in a way an implicature as it has world-to-mind fit. That is, knowledge, like language itself, is mostly constructed in a society, as per Wittegensteinian notions of language-games. In logic and grammar, sometimes questions are reduced to propositional form, for instance, in traditional sentence diagramming, the interrogative is placed as an object in a sentence; in pragmatics, the critical eye is placed on the context, and therefore is related to ideas about the cooperative principle. Like all utterances, one has to examine both the syntax and the semantics to fully resolve understanding of the question. For instance, some syntactical questions are actually statements and are known as rhetorical questions. Sometimes, questions can be uttered as performative acts. A simple example is when people utter "How are you?" and really just mean "Hello, I see and acknowledge you."
Frege and Tarski were both big on truth-conditional semantics, and as they were developing theories a hundred years ago, set questions somewhat aside, to focus on logical propositions, definitions, sense and reference, and the relationship between truth and meaning. Questions themselves, are one of the simplest ways to do philosophy, and Socrates use his zetetic method because much of cognition, prior to rigorous study relies on intuition. By asking questions, a person is then required to express sentences which themselves are taken to exist as representations of thought. The Greeks of course pioneered democracy and political science, and as such, needed to ask questions because unlike a tyranny where the will of the tyrannt is truth and law, a collective of people needs a way to resolve matters. As the article mentions, both inquiry and explanation are contingent upon questions, and questions themselves play a central role in the epistemological mechanisms, because such mechanisms are aspects of collective intentionality.
