Logical and non-logical connectives are explained in detail in Chapter 14. For the purposes of this chapter, it suffices to point out that a logical (or non-logical) connection between two bridi which differ only in a modal can be reduced to a single bridi with a connective between the modals. As a result, Example 15.1 and Example 15.2 mean the same thing:
15.1) la frank. bajra seka'a le zdani .ije la frank. bajra teka'a le zdani
Frank runs with-destination the house. And Frank runs with-origin the house.
Frank runs to the house, and Frank runs from the house.
15.2) la frank. bajra seka'a je teka'a le zdani
Frank runs with-destination and with-origin the house.
Frank runs to and from the house.
Neither example implies whether a single act, or two acts, of running is referred to. To compel the sentence to refer to a single act of running, you can use the form:
15.3) la frank. bajra seka'a le zdani ce'e teka'a le zdani
Frank runs with-destination the house [joined-to] with-origin the-house.
The cmavo “ce'e” creates a termset containing two terms (termsets are explained in Chapter 14 and Chapter 16). When a termset contains more than one modal tag derived from a single BAI, the convention is that the two tags are derived from a common event.
