Gendered words?
There are two types of gender, you have neutered (which is most if not all the words for the most part) and sexual (aaga) This could just be considered a word accessory (?), but for right now i’m calling it gendered until I can find a better name for it. To make something sexually based, you add it onto the base word, HOWEVER.If uk is involved then you add it after the uk. ( ie ()ukaaga )

Past, present and future
Technically everything unless specifically said is in present tense, due to mers not needing a reason to specifically state otherwise, since most things are talked about in the moment when comes to present tense. Past tense is Uni (taken from one of the ancient tongues and half mixed in with Inupiat language, mostly of the base word of unip(k) ) and is put before the word even begins with a hyphen in inbetween. Future tense is Stinn (once again the ancient tongues for the word sinna).
