Usage notes
Iushapagwai is often translated "marriage" because two or more people are living together in the same house, sharing property, and sometimes engaging in sex acts. However, the word is not in any way close to marriage as understood in the cultures of the modern world, nor does Zekaisivarsi have a word equivalent to English marriage. Some examples will help clarify the denotation of this word.
zu ye iushapagwai rira. zu ye jzair ziaqh, You and I are close friends. We can go into each other's homes without fear, (trusting neither shall do any evil).
iushapagwai zuye lijvaq aram. On account of our deep friendship, we can open up to each other (speak openly).
erayi zuye iushapagwai uramgalrae aie. We can have sex with each other (come upon each other) because we are so intimate.
Now you know that intimate friendship is what is meant by becoming one body and spirit.
