Understanding -si Ending Words in Finnish
Words that end in -si in Finnish are typically nouns or adjectives that belong to a specific declension group. Many of these words have roots that originally ended in -de, -te, -ne, or -le in the older form of the language. Over time, these endings became simplified to -si. Some common examples include:
- vesi (water)
- käsi (hand)
- lasi (glass)
- uusi (new)
Recognizing this group and its declension patterns is key to forming correct sentences and expressing yourself accurately in Finnish.
General Declension Rule for -si Words
When declining -si ending words, the -si typically changes to -de or another consonant combination, depending on the original stem. The transformation affects all grammatical cases, including the genitive, partitive, inessive, and others. Let’s look at the steps to decline these words:
Step 1: Identify the Stem
First, remove the -si ending to find the stem. Then, restore the original consonant, such as -de, -te, -ne, or -le, depending on the word. For example:
- vesi → vede-
- käsi → käde-
- lasi → lase-
- uusi → uude-
Step 2: Add the Case Endings
After restoring the stem, simply add the appropriate case ending. Here are a few examples using common cases:
- Genitive (ownership): -n
vesi → veden (of water) - Partitive (some/any): -tä or -a
vesi → vettä (some water) - Inessive (in): -ssä
vesi → vedessä (in water) - Illative (into): -en
vesi → veteen (into water)
