If the word ends with a vowel the e in 'en' is dropped, eg. kvinnan, flickan.
So is there an article for "the" in Swedish - or is 'en' always added to the end of the noun?
The article ”the” is just hooked onto the end of the word instead of being a separate word as in English. It’s either -en or -et depending on the gender of the word.
I guess I should go further into the course before asking this question, but is it like in Danish where if there's an adjective then den/det is added before the adjective?
Yes, but unlike Danish, Swedish has a triple definiteness: det stora huset for example. You’ll encounter plenty of examples later in the course.
'Man' can be pronounced in two ways. With short a and long n it means man or one. With long a and short n it means the mane of a horse. The difference can be seen in the definite forms, which are mannen and manen.
Because I think it's better to have it the way it is because when you say it mannen it feels like your having a good time
in my language 'mannen is plural for men. is that the same in swedish, or is it different?
Firstly 'man' is in the common case, so it uses '-n' instead of '-t'. Secondly, 'the man' is in the definitive form, so instead of using the standalone word 'en' which means 'a', it uses the suffix '-en', and doubles the 'n' from 'man' to keep the vowel the same length (in this case it's a short vowel, I believe), making mannen.
Note: In words ending in a vowel you generally just add '-n' for the definite, so fickan, soffan, skon, etc.
