"I am tall."
Translation:Ik ben lang.
Predicative adjactives (The man is tall; the girl is nice) do not get an -e.
My understanding is that "groot" can also be used to mean tall. Is there a reason this is not accepted? Is it a Dutch (from the Netherlands) vs Flemish difference?
Yes, it can. However there is a slight difference. The same as saying a big man instead of a tall man. Big and also groot implies the idea of fat or muscular, not tall in combination with thin. (Mager).
This doesnt make sense. Two problems ago it said that "lange" is tall and "lang" is long, which i confused before and got incorrect, and now it says that "lange" is long? Either there is an inconsistancy in this app or the dutch language is way more compicated than i thought.
Modern English has "tall" for vertical length (people, buildings, even mountains are "tall"). "Long" is nowadays reserved for horizontal length long trains, long fields, long distances - or extended periods of time. You can have a long journey, but not a tall one! However, historically we also find "long" meaning (vertically) "tall". The surname Longfellow speaks for itself. In relatively recent Irish history, two heroes of the liberation struggle were known as "the long fellow" (Eamon De Valera - tall and skinny) and "the big fellow" (Michael Collins - tall and built like a brick outhouse).
Is 'hebben jullie' 'do you have' as in only you (one person) or is it as in 'do y'all have'?
I don't know if it is a true cognate but in English someone who is tall (and thin) can be described as "lanky".
I don't understand the difference between "lang" and "lange" Just like in "rustig" and "rustige" Can someone help ?
There's no difference in the meaning of the words, the spelling is just altered slightly depending on the sentence structure (and as a consequence, there's a very slight change in pronunciation). See these notes, they'll explain when to use the different spellings:
I'm confused by this "lang" thing, because, as I hear, people also use word "hoog" to describe "tall". Can somebody explain, why Duo tells that my choise of "hoog" word is wrong in this particular case?
