Learn Italian: Senza un diploma, trovare lavoro è più difficile. - Without a diploma, finding work is more difficult.

Even though it ends in -a, diploma is a masculine noun. It belongs to a group of Italian words of Greek origin ending in -ma (like problema, sistema, and clima) that are actually masculine. Because it is masculine, it takes the indefinite article un.

How do you make diploma plural?

Because it is a masculine noun, its plural follows the regular masculine rule: the ending changes to -i. The plural is diplomi (and the definite plural is i diplomi).

The English translation uses 'finding', so why does the Italian use the infinitive trovare?

In English, we often use the '-ing' verb form when the verb acts as the subject of a sentence. In Italian, you must use the infinitive form (trovare) when a verb is used as a noun in this way. You cannot use the Italian gerund (trovando).

Why is there no article before lavoro?

Trovare lavoro is a common expression meaning 'to find work' in a general sense. While you can say trovare un lavoro ('to find a job'), dropping the article is very natural when talking about employment as a broad concept rather than one specific position.
