I often hear these mistakes made by German speakers who are learning English.
They say: I made a lot of photos in my holiday.
There are a couple of things wrong with this.
Firstly, make is the wrong verb. We don’t make photos we take them.
Secondly the preposition is wrong. We don’t say in my holiday we say on my holiday.
The correct sentence is: I took a lot of photos on my holiday.
Have fun learning English!
