I don't mean to be an a.ss but the word is actually a declension...I wanted to put that out there in case anyone wanted to research.
haha it's cool .. i actually never heard the proper english term of that word, only known it from latin lessons and my teacher would always call it that even tho he was american
and since english (and spanish) language don't have declensions, you rarely hear anyone mention it..
fu*k my teacher, props to you.
edit: just realized the irony of me calling english easy to learn then fu*king up words
but yea, i grew up speaking english
