Learn Romanian: Muncitorii lucrează aici.

In Romanian, the word for "the" attaches to the end of the noun. The base masculine word is muncitor (worker). The plural is muncitori (workers) ending with one -i. To say "the workers", you add a second -i as the definite article, resulting in muncitorii.

Is lucrează the singular or plural form of the verb?

It is both! For the verb a lucra (to work), the "he/she" form and the "they" form are exactly the same: lucrează. Here, because the subject is the plural muncitorii, we know it translates as "they work".

The noun is muncitorii, but the verb is lucrează. Can I use a verb that matches the noun?

Yes, you can! Romanian has two common verbs for "to work": a lucra and a munci. They mean the same thing and are highly interchangeable. You could absolutely say Muncitorii muncesc aici and it would be perfectly correct.

How do I pronounce the double "i" at the end of muncitorii?

A single -i at the end of a plural Romanian noun is usually a very short, almost whispered sound. However, when you have a double -ii, you pronounce it as a full, clear "ee" sound, much like the vowel sound in the English word "feet".
