Learn Romanian: Noi bem laptele rece din pahar. - We drink the cold milk from the glass.

Bem is the "we" form of the verb a bea (to drink). It is slightly irregular. The present tense forms are: eu beau (I drink), tu bei (you drink), el/ea bea (he/she drinks), noi bem (we drink), voi beți (you all drink), and ei/ele beau (they drink).

Why does laptele end in -le? I thought the word for milk was lapte.

You are right, lapte means milk. In Romanian, the word for "the" is attached to the end of the noun. Because lapte is a masculine noun ending in -e, it takes the ending -le to mean "the milk".

Why is the word order laptele rece instead of the other way around?

In Romanian, adjectives (describing words like rece) almost always come after the noun they describe. So, instead of saying "the cold milk", you say the equivalent of "the milk cold" (laptele rece).

The English translation says "from the glass", but pahar doesn't have an attached "the" ending. Why?

In Romanian, you usually drop the definite article (the "the" ending) after simple prepositions like din (from/out of), în (in), or pe (on). So, even though we mean "from the glass", we just say din pahar rather than din paharul.
