Learn Romanian: Restaurantul are cincizeci de angajați. - The restaurant has fifty employees.

In Romanian, whenever you count 20 or more of something, you must place the preposition de between the number and the noun. Since cincizeci means 50, we have to say cincizeci de angajați (literally "fifty of employees"). For numbers 1 through 19, you don't use de.

How is the number cincizeci built?

It is made by combining cinci (five) and zeci (tens, which is the plural of zece). So cincizeci literally means "five tens". This is the standard pattern for multiples of ten in Romanian.

Why does the sentence start with Restaurantul instead of just Restaurant?

The -ul added to the end of the word is the Romanian definite article, meaning "the". Unlike English, Romanian attaches "the" to the end of masculine and neuter nouns. Restaurant means "restaurant", while Restaurantul means "the restaurant".

What is the singular form of angajați, and why does it end in a ț here?

The singular form is angajat (employee). Because it is a masculine noun, it becomes plural by adding an -i to the end. Notice that the final t in angajat changes to a ț when the -i is added. This is a very common sound and spelling change in Romanian plurals.
