Learn Italian: Un tale livello di arroganza suscita sempre problemi. - Such a level of arrogance always provokes problems.

In Italian, when using tale to mean "such a", the indefinite article comes before tale. You literally say "a such level" (un tale livello), whereas English puts the article after "such".

If I wanted to say "Such levels of arrogance", how would the phrase un tale livello change?

It would become tali livelli. The adjective tale behaves like other adjectives ending in -e; it changes to -i for both masculine and feminine plurals. Notice that the article drops entirely in the plural, just like in English ("such levels").

Does un tale always mean "such a"? I remember seeing it translated as "a certain person".

It depends on the context. Because it modifies the noun livello here, it acts as an adjective meaning "such a". If it were used as a pronoun on its own (e.g., ho visto un tale - I saw a certain guy), or before a name (e.g., un tale Marco), it means "a certain person".

The verb suscita translates to "provokes" here. Is it a common verb to use with problemi?
