Questions & Answers about Penso que aquesta idea és important.

Why does the sentence start with Penso and not with a subject like Jo penso?

In Catalan, the subject pronoun is often left out because the verb ending already tells you who the subject is.

• penso = I think
• The -o ending shows it is first person singular

So:

• Penso que aquesta idea és important. = I think that this idea is important.
• Jo penso que aquesta idea és important. also works, but jo is usually added only for emphasis, contrast, or clarity.

For example:

• Jo penso això, però ell no. = I think that, but he doesn’t.
