+## Discourse Structure
+
+Conversationally, a lot of things in L'ewa grammar get dropped unless it's
+ambiguous. The I/yous that get tacked on in English are completely unneeded. A
+completely valid conversation could look something like this:
+
+```
+<Mai> xoi
+<Cadey> xoi
+<Mai> xoi madsa?
+<Cadey> lo spalo
+```
+
+And it would roughly equate to:
+
+```
+<Mai> Hi
+<Cadey> Hi, you doing okay?
+<Mai> Yes, have you eaten?
+<Cadey> Yes, I ate an apple
+```
+
+People know when they can speak after a sufficient pause between utterances.
+Interrupting is not common but not a social faux-pas, and can be used to stop a
+false assumption from being said.

+## Formality
+
+The informal dialect of L'ewa drops everything it can. The formal dialect
+retains everything it can, to the point where it includes noun phrase endings,
+the verb signaler, ka/ke/ku and every single optional particle in the language.
+The formal dialect will end up sounding rather wordy compared to informal slangy
+speech. Consider the differences between informal and formal versions of "I eat
+an apple":
+
+```
+mi madsa lo spalo.
+```
+
+```
+ka mi ko xi ke madsa ku lo spalo ko.
+```
+
+Nearly all of those particles are not required in informal speech (you could
+even get away with `madsa lo spalo` depending on context), but are required in
+formal speech to ensure there is as little contextual confusion as possible.
+Things like laws or legal rulings would be written out in the formal register.

+## Information Structure
+
+L'ewa doesn't have any particular structure for marking previously known
+information, as normal sentences should suffice in most cases. Consider this
+paragraph:
+
+```
+I saw you eat an apple. Was it tasty?
+```
+
+Since `an apple` was the last thing mentioned in the paragraph, the vague "it"
+pronoun in the second sentence can be interpreted as "the apple".
+
+L'ewa doesn't have a way to mark the topic of a sentence, that should be obvious
+from context (additional clauses to describe things will help here). In most
+cases the subject should be equivalent to the topic of a sentence.
+
+L'ewa doesn't directly offer ways to emphasize parts of sentences with phonemic
+stress like English does (eg: "I THOUGHT you ate an apple" vs "I thought you ATE
+an apple"), but emotion words can be used to help indicate feelings about
+things, which should suffice as far as emphasis goes.

+## Utterances
+
+An utterance in L'ewa is anything from a single content word all the way up to
+an entire paragraph of sentences. An emotion particle can be a complete
+utterance. A question particle can be a complete utterance, anything can be an
+utterance. A speaker may want to choose more succinct options when the other
+detail is already contextually known or simply not relevant to the listener.
+
+L'ewa has a few discourse particles, here are a few of the more significant
+ones:
+
+| L'ewa | Function                                             |
+|-------|------------------------------------------------------|
+| xi    | signals that the verb of the sentence is coming next |
+| ko    | ends a noun phrase                                   |
+| ka    | marks something as the subject of the sentence       |
+| ke    | marks something as the verb of the sentence          |
+| ku    | marks something as the object of the sentence        |
