Okay kiddo, so have you ever played the question game where you ask someone a question and they have to answer it with a different question? Well, inquisitive semantics is kind of like playing that game with words and sentences.
You see, sometimes when we ask a question, we actually mean something else. For example, if someone asks "Do you have the time?" they probably don't just want to know what time it is. They might also be trying to figure out if you're available to do something at a certain time. So inquisitive semantics helps us figure out the real meaning behind questions like these.
Now, there are different ways to express the same question. For example, you could ask "Do you have the time?" or "What time is it?" or even "Can you tell me the time?" These might seem like different questions, but they all have the same meaning. So inquisitive semantics helps us figure out the underlying question that's being asked, regardless of how it's phrased.
To do this, we use something called "possible worlds." A possible world is like a different version of reality that shows what could have happened if things were different. So when we ask a question, we're really asking about a possible world where the answer to that question is different.
For example, if I asked "Is the sky blue?" I'm really asking about a possible world where the sky is not blue. And if you answer "Yes," you're telling me that in that possible world, the sky is indeed blue. If you answer "No," you're telling me that in that possible world, the sky is some other color.
The cool thing about inquisitive semantics is that it helps us understand not just questions, but also statements and other types of sentences. For example, if I say "John kicked the ball," I might be trying to convey different things depending on the context. Maybe I'm just stating a fact, or maybe I'm trying to emphasize how hard John kicked the ball, or maybe I'm trying to tell you that John shouldn't have kicked the ball. Inquisitive semantics helps us figure out what I really mean by that sentence depending on the context.
So there you have it, inquisitive semantics is a way of understanding the true meaning behind words and sentences by exploring different possible worlds. Isn't language fascinating, even for a five-year-old?
