So far we have seen sentences that differ in all components, and require bridi connection; sentences that differ in one sumti only, and permit sumti connection; and sentences that differ in the selbri and possibly one or more sumti, and permit bridi-tail connection. Termset logical connectives are employed for sentences that differ in more than one sumti but not in the selbri, such as:

The Lojban version of Example 14.71 requires two termsets joined by a logical connective. A “term” is either a sumti or a sumti preceded by a tense or modal tag such as pu or bai. Afterthought termsets are formed by linking terms together by inserting the cmavo ce'e (of selma'o CEhE) between each of them. Furthermore, the logical connective (which is a jek) must be prefixed by the cmavo pe'e (of selma'o PEhE). (We could refer to the combination of pe'e and a jek as a “pehejek” , I suppose.)

The literal translation uses “[plus]” to indicate the termset connective, and “[joint]” to indicate the position of the logical connective joint. As usual, there is an equivalent bridi-connection form:

which illustrates that the two bridi differ in the x₂ and x₃ places only.

What happens if the two joined sets of terms are of unequal length? Expanding to bridi connection will always make clear which term goes in which place of which bridi. It can happen that a sumti may fall in the x₂ place of one bridi and the x₃ place of another:

can be clearly understood by expansion to:

So le briju is your origin but my destination, and thus falls in the x₂ and x₃ places of klama simultaneously! This is legal because even though there is only one selbri, klama , there are two distinct bridi expressed here. In addition, mi in Example 14.74 is serving as a termset containing only one term. An analogous paradox applies to compound bridi with tail-terms and unequal numbers of sumti within the connected bridi-tails:

means that I go to the market from the office, and I walk to the office; le briju is the x₃ place of klama and the x₂ place of dzukla.

Forethought termsets also exist, and use nu'i of selma'o NUhI to signal the beginning and nu'u of selma'o NUhU (an elidable terminator) to signal the end. Nothing is inserted between the individual terms: they simply sit side-by-side. To make a logical connection in a forethought termset, use a gek, with the gek just after the nu'i , and an extra nu'u just before the gik:

Note that even though two termsets are being connected, only one nu'i is used.

The grammatical uses of termsets that do not contain logical connectives are explained in Section 9.8 , Section 10.25 , and Section 16.7.
