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 16 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 6 . |
| 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 5 . |
| 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 fu'ivla. See Chapter 4 . |
