Questions & Answers about Bu markaların hepsini puanladık.
Why does hepsi have an -ni at the end in this sentence?
The word hepsi (all of them) has the 3rd person possessive suffix -si. Because it is the direct object receiving the action of the verb puanladık (we rated), it needs the accusative case. To add the accusative -i, we first need the buffer letter -n-, making it hepsini.
Why is markalar (brands) written with the genitive -ın suffix?
In Turkish, saying "all of the brands" requires a genitive-possessive construction. You attach the genitive suffix -ın to the group you are choosing from (markaların, "of the brands") and the possessive suffix -si to the indefinite pronoun (hepsi, "all of them").
If we are talking about "these" brands, why don't we use the plural bunlar?
When a demonstrative word like bu, şu, or o is used as an adjective right before a noun, it always stays singular in Turkish. Even though the brands are plural, we say bu markaların instead of bunlar markaların.
How do we get the verb puanladık from the noun puan (point)?
