Learn French: Il prend une glace et un jus. - He is having an ice cream and a juice.

In French, it is very common to use the verb prendre (to take) when talking about 'having' food or a drink, especially at a café or restaurant. While you could perfectly say il boit un jus (he is drinking a juice), il prend un jus (he is having a juice) is how a native speaker will often describe having a drink or meal.

Is the 's' at the end of 'jus' pronounced?

No, the 's' in jus is completely silent. In French, most consonants at the end of a word are silent unless they link to a vowel in the next word.

Why do we use 'une' for ice cream but 'un' for juice?

French nouns are either masculine or feminine, and the words for 'a' or 'an' must change to match. Glace (ice cream) is feminine, so it takes une. Jus (juice) is masculine, so it takes un.

What verb does 'prend' come from?

It comes from the irregular verb prendre, which means 'to take'. For il (he) or elle (she), the correct form is prend. Notice that the 'd' at the end of this word is also silent!
