"Vorbești ca un politician."

Translation: You speak like a politician.

[ariawave]

"Speak as" implies "speaking in the capacity of" rather than "speaking similarly to"

[TurchynSlava]

Why it doesn't accept "You speak as a politician"?

[WestleyT]

That is awkward phrasing in English. It would have to read "you speak as a politician speaks" or "as a politician does" but this sounds bery formal and rarely woukd spoken this way. The "like" translation is the most natural sounding
