Ett or et?
Ett means one, specifically. Et, in contrast, usually means a or an.
That's right "ett" and "én" are numerals, "et" and "en" are articles.
What about for 'ei'? Is the numeral then 'éi'?
It is just ei.
However, in the dictation exercise it is impossible to distinguish. But maybe "ett" makes more sense because of the second part, which contains the numeral "to".
Yes, you are clearly counting.
I swear this is a play on a German tree sentence somehow. Maybe I'm wrong, though.
"Kinn" in German means "chin", a false friend in this case.
You need two so you can turn the other one.
