Questions & Answers about Quel comportamento preoccupa tutti.

Why is it quel comportamento and not quello comportamento?

Because quello changes form depending on the noun that follows, much like the definite article.

Before a masculine singular noun beginning with most consonants, quello becomes quel.

So:

• quel comportamento = that behavior
• quello studente = that student
• quell’amico = that friend (before a vowel)

Since comportamento is masculine singular and starts with c + vowel, quel is the correct form.

What part of speech is quel here?

Here quel is a demonstrative adjective. It points to a specific thing: that behavior.

It goes directly before the noun comportamento and functions like English that in that behavior.

Why is there no article before comportamento?

Because quel already determines the noun.

In Italian, you normally do not say il quel comportamento. The demonstrative replaces the article:

• il comportamento = the behavior
• quel comportamento = that behavior

So quel is doing the job of specifying the noun by itself.

Why is the verb preoccupa and not some other form?
