"That is an excellent statue."

Translation: Εκείνο είναι ένα άριστο άγαλμα.

[HellasCad]

Why not υπέροχο;

[LindaSpiroXhardo]

Why not Εξαίσιο?

[soffod]

What about εξαιρετικό?

Answers please to the questions below. Before you have said "άριστο" is "optimal" which would not be correct here?

[G.Georgopoulos]

The best translation of "optimal" is "ο καλύτερος δυνατός/ο βέλτιστος"="the best possible" ;)

Why is "εξαιρετικό άγαλμα" wrong? I look for the translation of "excellent" in a dictionary and I found "εξαίρετος" or "εξαιρετικός" before "άριστος".

[G.Georgopoulos]

Technically, there are some nuances between these words, but they have come to be interchangeable in many cases, so yes, it will be added.
