I am confused about the usage of "had" along with "forget". Let's take some serious example.
People usually took bath in rivers. Now, they've changed their tradition. I mean, they're bathing in their home, wasting a lot of water.
I want to say this using "forget". When I think of it, it usually comes to me like this:
The humans had forgot the rivers.
I'm also confused with this phrase. Is this right? Or instead does forgotten play a role? As it has already happened in the past, how can I phrase it? Any alternative choice that I can use here in order to avoid my confusion?
