What would it be if it was "Karoto povas estas blanka"?

[Luis_Domingos]

It just wouldn't be correct at all.

[chocotaco_]

Oh, ok. Thanks

"A carrot can is white."

[arbaro]

There are definitely exceptions, but a good rule of thumb is that you shouldn't have multiple non-infinitive verbs in a row. :)

Why not "Karoto povas blanka." ?

"Karoto povas blanki" is accepted. You need to have that extra verb.

[LindaAustralie1]

That would make the povas into a verb and you cannot 'white'. You need to have the 'to be' in there to show that it IS white. To English speakers, Esperanto does shorten some things down, however not this much. In other areas, Esperanto speaks as an olde language and adds more into it, making it almost poetic.
