I had a question about suffixes. I may have asked this before but I often see, in anime, the suffix =tachi.
I know it’s generally understood as pluralizing a noun. For example: Atashi-tachi or something similar.
Yet, when asked, in the context of a Japanese class in college. My professor marked it wrong when the question called for a plural. I don’t remember what the question was, nor what I put. However, maybe those that live out in Japan can guess as to why?
Thanks in advance.
