Learn Romanian: Televizorul este în sufragerie.

In Romanian, the word for "the" (the definite article) attaches to the end of the noun instead of coming before it as a separate word. Televizor means "television", and adding -ul makes it televizorul ("the television").

The English translation says "in the living room", so why doesn't sufragerie have a "the" attached to it?

After many simple prepositions like în (in), Romanian usually drops the definite article if the noun stands alone. You just say în sufragerie (literally "in living room"). If you added a describing word, like "in the big living room", the article would come back.

I often see e instead of este for "is". Can I use e in this sentence?

Yes, you can! Televizorul e în sufragerie is perfectly correct and very common in everyday spoken Romanian. Este is slightly more formal in writing, but both mean exactly the same thing.
