I have been studying japanese for some time now (my level floating somewhere between beginner and intermediate), and the particle も has confused me.
I already know it works kind of like "too" or "also" Ex: 私も。「わたしも」== "Me too"
However, I've seen sentences where this meaning of "too" isn't present
Ex:
雨はもう3日「も」降っています
(It's been raining for nearly three days now)
Can someone give me a general overview of what も can represent, and in what contexts the meaning of it will change. Thank you.
