Words of two syllables ending in -a can inflect in two ways, depending on the vowel in the first syllable. I’ve affectionately named these groups “kissa-words” and “koira-words”.

Read more about the difference between kissa- and koira-words (section 2.3.1 and 2.3.2.)

• A kissa-word is a word of two syllables, ending in an -a, which has the vowel -i, -a, or -e in the first syllable. These words will get -oja in the plural partitive (eg. kissa > kissoja)
• A koira-word is a word of two syllables, ending in an -a, which has the vowel -o, or -u in the first syllable. There words will get -ia in the plural partitive (eg. koira > koiria)

This exercise contains easy wordtypes only.

The rules:

By changing word order like this, we create existential sentences. The sentence “Pojat leikkivät puistossa” tells us where the boys are playing. In contrast with that, the sentence “Puistossa leikkii poikia” tells us what’s happening in the park. In this exercise, you’re turning “The boys are playing in the park” type of sentences into existential “There are boys playing in the park” type sentences.
