"She is a woman."
Translation:Hon är en kvinna.
'en' and 'ett' both means a(n) in English. like (a boy=en pojke). (en älg=a moose). 'ett' is for neuter one, like (an apple=ett äpple). (an animal=ett djur).
'ett' definitely is for objects and Yes you are right, but 'en' could be both for living things and object as well such as (en pojke=a boy) (a bird=en fågel) or even objects like (a dress=en klänning.) (a T-shirt=en tröja.)
On a Mac you just type the "Option" key, then the "u" to get the accent mark, and then you type the letter you want that accent to go on. On Windows it is of course more complicated. One good option is to install the US International Keyboard and then follow the instructions on the Internet about how to type that.
