I was wondering if there was a general rule for what reading to use in certain situations with 人. So far it seems to be pretty random when to use ひと, にん or じん. The only consistent one atm seems to be にん for the counter for people. Perhaps the further I get into my grammar study there will be a explanation?
I have managed to figure out that the reading for 月 as がつ is usually only used when describing the actual months e.g. January, Feb etc. Where as げつ is more for the general term month, e.g. next month, last month.
Is there any one general rule you guys use to help you remember what reading to use for 人?
Thanks
