In Japanese, 人is an on'yomi (Chinese-derived) reading of the kanji meaning person, human, or people. It is primarily used as a suffix to denote nationality, origin, or a specific type of person such as 日本人- Japanese person or 主人- Master/Husband
That is how Fuguro works. It brings -人 back for review right before you forget it, each time a little later, until it sticks for good. You hear it spoken aloud, and you meet it again in stories you can already read. The first five levels are free.
