Thank you for the link. My wife left Denmark 35 years ago and does not recall the use acents. Languages change.

I like the inclusion of 'duck' in my word choice options :)

Me too but its en not and

[PiIeLjTn]

"you are someone interesting" seems to be more idiomatic

[Patsy536249]

Why first en has no accsnt mark and second does

[sll-ttt]

Because the first one is an article and the second is a number.
en = a ; én = one. But generally en is one too

en mand = a man ; én mand = ONE man: But en mand to kvinder works too : one man 2 women

It is not mandatory to use the accented letters é, ét. It is if you want to insist ( or emphazise ??) on the fact that it is a number and not an article

In the sentence above there is really no reason to use it except for educational purpose

[lisamich]

The accent, é, does not, to my knowledge, exist in Danish.

[lisamich]

Ok, I did more research, é does exist. However, just putting it here for beginners without any explanation is hardly pedagogically useful. It only serves to create confusion.
