Questions & Answers about Her üzüm köküne yedişer litre su verelim.
Why does yedişer use -şer instead of just -er?
The distributive suffix is -ar or -er depending on vowel harmony. However, because yedi (seven) ends in a vowel, we must add the buffer letter ş to prevent two vowels from clashing. So it becomes yedişer (seven each).
Does yedişer mean exactly the same thing as yedi?
Not quite! While yedi just means "seven", yedişer adds the meaning of "seven each". In this sentence, it clarifies that each root gets seven liters, rather than seven liters being divided among all the roots.
Let's break down the word köküne. Why are there extra letters after kök (root)?
First, we have the compound noun üzüm kökü (grape root), where the -ü is a possessive suffix linking the two words. Then, the verb vermek (to give) requires the dative case (giving to something). We add the dative suffix -e, but we always need the buffer letter -n- between a third-person possessive suffix and a case marker. So: kök + ü + n + e = köküne.
Why isn't litre pluralized (like "litreler") since it's "seven liters"?
