I have learned a lot about the first, second and third conditionals, but something that always crossed my mind is why they are called 1st, 2nd and 3rd.
Does anyone have an explanation for this?
There are other terminologies, such as Type I, II and III Conditionals, but as far as I researched, there's nothing further than this, they're always named with numbers.
Are there any other names we can name these conditionals?
