"I am not sleeping, but I'm reading" should be accepted? shoudn't be?
why is sleep in the definite form?
It is indefinite but, since it is an "-ik" type verb (3rd person singular is "alszik"), the first person singular is "-m", not "-k".
These verb types are really not very clear in the course. Not sure how this is taught in other languages, but I am a bit lost with hungarian, that's for sure :)
there are good tips and there are "less good" ones. It might just be that hungarian is so different from other languages I have experience with.
