I'm starting to think that the guy who create the sentences has a drinking problem
I'm starting to think that I was the one who created the sentences but was too drunk to remember
...since there is just one present tense in Norsk, am I right, am I, am I? :)
"En øl" is used about a unit of beer and is a countable noun, "et øl" is used about a type of beer, or in a general sense, and is an uncountable noun.
I do not believe so. "En øl" means "a beer," thus the definite would be "ølen." "Ølet" would imply that "a beer" would be "et øl" instead of " en øl."
