The full set of rules for inserting ``na'', ``se'', and ``nai'' into any connective is:

Afterthought logical connectives (eks, jeks, giheks, ijeks):

Negate first construct:

place ``na'' before the connective cmavo (but after the ``.i'' of an ijek).

Negate second construct:

place ``nai'' after the connective cmavo.

Exchange constructs:

place ``se'' before the connective cmavo (after ``na'' if any).

Forethought logical connectives (geks, guheks):

Negate first construct:

place ``nai'' after the connective cmavo.

Negate second construct:

place ``nai'' after the ``gi''.

Exchange constructs:

place ``se'' before the connective cmavo.

Non-logical connectives (joiks, joigiks):

Negate connection:

place ``nai'' after the connective cmavo (but before the ``gi'' of a joigik).

Exchange constructs:

place ``se'' before the connective cmavo.
