x1 is a material conditional/'IF' statement (logical statement) saying that x2 (du'u) logically implies x3 (du'u) ("x3 is true if x2 is true; if x2, then x3; x2 being true is sufficient to guarantee the truth of x3").

Beware the order of x3 (the consequent) and x2 (the antecedent/sufficient condition). This word is to "na ja" approximately as kanxe is to je. See also: kanxe, vlina, ribga, naja, .ifle, fi'ei.

x1 is a logical statement of proposition-equivalence/is a biconditional/'IFF' statement saying that x2 (du'u) is true if and only if x3 is true ("x2 is logically equivalent to x3; x2 being true is sufficient and necessary for guaranteeing the truth of x3; x2 iff x3").
