Questions & Answers about Kukot istuvat vanhalla aidalla.
Why does kukot have a weak grade (one 'k'), but its partitive plural form keeps the strong grade?
Consonant gradation is all about closed versus open syllables. The nominative plural ending -t closes the syllable, triggering the weak grade (so kukko becomes kukot). The partitive plural is kukkoja. Because the ending -ja doesn't close the syllable, the double 'k' stays strong!
We are currently learning the partitive plural. Why is kukot in the nominative plural here instead?
Because we are talking about specific roosters. Using the nominative plural kukot means 'The roosters'. If we wanted to express an indefinite amount ('Some roosters'), we would use the partitive plural and typically put the location first: Vanhalla aidalla istuu kukkoja.
I see aidalla comes from aita (fence). How does its consonant gradation compare to its partitive plural form?
Just like with kukko, the word aita has a strong consonant ('t') that weakens to 'd' when the syllable is closed. The adessive ending -lla closes the syllable, giving us aidalla. In the partitive plural (aitoja), the syllable is open, so the strong 't' comes back!
Why do both vanha and aita take the -lla ending here?
