Is There a Relationship Between Information and Sentence?

We use sentences to express information, but we can lieve things without using any and merely possible agents can believe things without using the english sentence that we use. Russell and frega thought that there was such a thing. They could not figure out what it was. And they ended up giving up o idea. Much of the tradition turned to sentences and truth conditions. Then i got augmented to truth relative to a possible world state. And then propositions came back again, that they were sets of possible world state or impossible worlds. So we know it can't be those things. What can it be?
