"We have waited a long time, but he has not come."

Translation: Wij hebben een lange tijd gewacht, maar hij is niet gekomen.

[Moshe881028]

why is this is gekomen rather than heeft gekomen?

[VanitaBalf]

I think verbs of motion need zijn instead of hebben.

[AmitabhS.B]

Good question!

[vcuauhtemoc]

Just a general complaint but i think a sentence this long should somehow only partially penalize when you confuse only one word like 'is'. Any language exam i have taken would have done so since there are multiple things that can be graded for in this sentence.

It is frustrating, but then it's always gekomen zijn - if Duo let it pass here you might not learn that.

It is particularly difficult for dyslexic people to see the difference.

[Hamborg]

I would in general agree especially if you translate back to English (or what ever language) and you make an english gamma-mistake like "he run" (without "-s").. But in this case, as Raahiba says, the 'is' is rather important for the past present.

[H_Butler]

why is "gekomen" not "gekomt"?

[Raahiba]

'Komen' is irregular: ik kom, ik kwam, ik ben gekomen.

Thanks! Haha I realized after I wrote this that maybe I should read the lesson notes.

[Dono.1802]

Sometimes I see een lange tijd and sometimes lange tijd. What's the difference?

[Shahram23967]

It's not "gewachten"?

Wij wachtte een lange tijd, maar hij kwam niet.

I can never remember to put is instead of heeft. maar hij heeft niet gekomen.
