It is from the demonic tongue of My native realm. “Haewa” means love. In actuality, it is a verb. I’ve not had the heart to correct her, as I find it endearing.
You might have noticed I also call her “Zoqa”, which means Mate.
In the demonic tongue, “Zoqa” is the only term of endearment for one’s most beloved and dearest intimate companion. Demons have their flaws, to be certain, but one of the better parts of their nature is they mate for life.
Grace has been doing her level best to learn the common demon tongue. There is a slightly flawed translator available here, but it can help if you wish to learn the basics of the language.
