Questions & Answers about Bu üç araba çok ucuz.
Why is it araba and not arabalar if there are three of them?
In Turkish, whenever you use a number before a noun, the noun must stay in its singular form. You say üç araba (literally "three car"), never üç arabalar. This is a very strict and important rule to remember!
The translation says "These", but doesn't bu mean "This"? Why not use bunlar?
You are exactly right that bu means "this" and bunlar means "these". However, when pointing words like bu are used directly in front of a noun phrase to describe it, they never take a plural ending. Because üç araba is grammatically singular in Turkish, the pointing word bu stays singular as well.
Where is the word for "are" in this sentence?
Turkish doesn't use a separate word for "is" or "are" in simple descriptive sentences like this one. Simply putting the subject (Bu üç araba) and the description (çok ucuz) together creates a complete sentence.
Does çok always mean "very"?
It depends on what follows it! When çok comes before an adjective (like ucuz, meaning cheap), it translates to "very". If it comes before a noun, it usually means "a lot of" or "many".
