# Chapter 6. To Speak Of Many Things: The Lojban sumti

## 6.1. The five kinds of simple sumti

If you understand anything about Lojban, you know what a sumti is by now, right? An argument, one of those things that fills the places of simple Lojban sentences like:

Example 6.1.

 mi klama le zarci I go-to the market

In Example 6.1, mi and le zarci are the sumti. It is easy to see that these two sumti are not of the same kind: mi is a pro-sumti (the Lojban analogue of a pronoun) referring to the speaker, whereas le zarci is a description which refers to something described as being a market.

There are five kinds of simple sumti provided by Lojban:

1. descriptions like le zarci, which usually begin with a descriptor (called a gadri in Lojban) such as le;

2. pro-sumti, such as mi;

3. names, such as la lojban., which usually begin with la;

4. quotations, which begin with lu, le'u, zo, or zoi;

5. pure numbers, which usually begin with li.

Here are a few examples of each kind of sumti:

Example 6.2.

 e'osai ko sarji la lojban. [request] [!] You [imperative] support that-named Lojban.

Example 6.2 exhibits ko, a pro-sumti; and la lojban., a name.

Example 6.3.

 mi cusku lu e'osai li'u le tcidu I express [quote] [request] [!] [unquote] to-the reader.
