Learn Romanian: Telefonul nou este scump? - Is the new phone expensive?

In Romanian, adjectives almost always go after the noun they describe. Because of this rule, instead of saying 'the new phone', you say 'the phone new' (telefonul nou).

Why do we use the specific forms nou and scump here?

These are the masculine singular forms of the adjectives. The word telefon is a neuter noun. Remember that in Romanian, neuter nouns act exactly like masculine nouns when they are singular, so any adjectives describing them must take the masculine singular form.

Where is the word for 'the' in telefonul?

It is attached right to the end of the word! The base noun is telefon, and adding the suffix -ul acts as the definite article, making it telefonul (the phone).

How can this be a question if the words are in the exact same order as a normal sentence?

In Romanian, you do not need to change the word order or add helper words like 'is' or 'does' to the front to make a yes/no question. You simply use the statement word order and raise your voice at the end of the sentence when speaking.
