2.18. Lojban grammatical terms

Here is a review of the Lojban grammatical terms used in this chapter, plus some others used throughout this book. Only terms that are themselves Lojban words are included: there are of course many expressions like indicator in Chapter 2 that are not explained here. See the Index for further help with these.

bridi predication; the basic unit of Lojban expression; the main kind of Lojban sentence; a claim that some objects stand in some relationship, or that some single object has some property.
sumti argument; words identifying something which stands in a specified relationship to something else, or which has a specified property. See Chapter 2.
selbri logical predicate; the core of a bridi; the word or words specifying the relationship between the objects referred to by the sumti. See Chapter 2.
cmavo one of the Lojban parts of speech; a short word; a structural word; a word used for its grammatical function.
brivla one of the Lojban parts of speech; a content word; a predicate word; can function as a selbri; is a gismu, a lujvo, or a zi'evla. See Chapter 2.
gismu a root word; a kind of brivla; has associated rafsi. See Chapter 2.
lujvo a compound word; a kind of brivla; may or may not appear in a dictionary; does not have associated rafsi. See Chapter 2 and Chapter 2.
zi'evla a borrowed or a priori word; a kind of brivla; may or may not appear in a dictionary; expresses concepts that are difficult to express using gismu or lujvo; does not have associated rafsi. See Chapter 2.
rafsi a word fragment; one or more is associated with each gismu; can be assembled according to rules in order to make lujvo; not a valid word by itself. See Chapter 2.
tanru a group of two or more brivla, possibly with associated cmavo, that form a selbri; always divisible into two parts, with the first part modifying the meaning of the second part (which is taken to be basic). See Chapter 2.
selma'o a group of cmavo that have the same grammatical use (can appear interchangeably in sentences, as far as the grammar is concerned) but differ in meaning or other usage. See Chapter 2.
