"I am short, I am not tall."

Translation: Eu sunt scund, nu înalt.

[GeoMan2]

"am" is english, you need second "sunt". If you used aux. vb. "to have", then it's not correct.

[Loltiker]

short means scurt not scund

[--Narcisz--]

No, that means also "scund", if you talk about people, and if you talk about objects or the length of something, then means "scurt".

[ham_freedom]

scurt is for length of objects,
scund describes the height of someone.

[ArguingInElvish]

Can't I say, "Eu sunt scund, nu am înalt" ?
