Last and (as a matter of fact) least: a logical connective is allowed between abstraction markers of selma'o NU. Jeks are the appropriate connective.
le | mikce | cu | se | cinri | le | pu'u | jenai | za'i | mi | sipna |
The | doctor | is-interested-in | the | process-of | and-not | state-of | me | sleeping. |
The doctor is interested in the process of me sleeping but not in the state of me sleeping. |
As with tenses and modals, there is no forethought and no way to override the left-grouping rule.
Logical connectives and abstraction are related in another way as well, though. Since an abstraction contains a bridi, the bridi may have a logical connection inside it. Is it legitimate to split the outer bridi into two, joined by the logical connection? Absolutely not. For example:
mi | jinvi | le | du'u | loi | jmive |
I | opine | the | fact-that | a-mass-of | living-things |
cu | zvati | gi'onai | na | zvati | vau | la | .iupiter. |
(is-at | or-else | is-not | at) | that-named | Jupiter. |
I believe there either is or isn't life on Jupiter. |
is true, since the embedded sentence is a tautology, but:
mi | jinvi | le | du'u | loi | jmive | cu | zvati | la | .iupiter. |
I | opine | the | fact-that | a-mass-of | living-things | is-at | that-named | Jupiter |
.ijonai | mi | jinvi | le | du'u | loi | jmive |
or-else | I | opine | the | fact-that | a-mass-of | living-things |
na | zvati | la | .iupiter. |
isn't-at | that-named | Jupiter |
is false, since I have no evidence one way or the other (jinvi requires some sort of evidence, real or fancied, unlike krici).
