Comparison of Adjectives in Finnish
Vertailu
Overview
Comparing things is a fundamental part of communication, and Finnish handles comparisons through specific adjective forms at the A2 level. Finnish has three degrees of comparison: positive (the basic form), comparative (more), and superlative (most). The comparative is formed with the suffix -mpi and the superlative with -in.
Unlike English, which uses both inflection ("bigger") and periphrasis ("more beautiful"), Finnish consistently uses suffixes for all adjectives. There is no equivalent of "more" + adjective — every adjective takes the comparative and superlative endings directly.
The comparative and superlative forms also decline through all Finnish cases, maintaining adjective agreement with the noun. This adds complexity but follows predictable patterns that build on your existing case knowledge.
How It Works
Comparative (-mpi)
| Positive | Comparative | English |
|---|---|---|
| iso (big) | isompi | bigger |
| pieni (small) | pienempi | smaller |
| kaunis (beautiful) | kauniimpi | more beautiful |
| hyvä (good) | parempi | better (irregular) |
| pitkä (long) | pidempi | longer |
| lyhyt (short) | lyhyempi | shorter |
Superlative (-in)
| Positive | Superlative | English |
|---|---|---|
| iso | isoin | biggest |
| pieni | pienin | smallest |
| kaunis | kaunein | most beautiful |
| hyvä | paras | best (irregular) |
| pitkä | pisin | longest |
| lyhyt | lyhin | shortest |
Comparison structure
| Pattern | Finnish | English |
|---|---|---|
| A is ADJ-er than B | A on ADJ-mpi kuin B | A is more ADJ than B |
| A is the ADJ-est | A on ADJ-in | A is the most ADJ |
Case declension of comparatives
The comparative stem for case forms uses -mpa-/-mpä-:
| Case | isompi (bigger) | Example |
|---|---|---|
| Nominative | isompi | Tämä on isompi. |
| Genitive | isomman | isomman talon |
| Partitive | isompaa | isompaa taloa |
| Inessive | isommassa | isommassa talossa |
Irregular comparisons
| Positive | Comparative | Superlative | English |
|---|---|---|---|
| hyvä | parempi | paras | good/better/best |
| huono | huonompi | huonoin | bad/worse/worst |
| paljon | enemmän | eniten | much/more/most |
| vähän | vähemmän | vähiten | little/less/least |
| pitkä | pidempi | pisin | long/longer/longest |

Common Mistakes
Using "enemmän" instead of comparative suffix
- Wrong: Tämä on enemmän iso kuin tuo.
- Right: Tämä on isompi kuin tuo.
- Why: Finnish always uses the comparative suffix (-mpi), never a separate word for "more" with adjectives. Enemmän is the comparative of paljon (much) and is used only with quantity.
Forgetting irregular forms
- Wrong: hyvämpi, hyvein
- Right: parempi, paras
- Why: The most common irregular comparisons (hyvä/parempi/paras) must be memorized. They cannot be formed with regular suffixes.
Not declining the comparative
- Wrong: Asun isompi talossa.
- Right: Asun isommassa talossa.
- Why: Comparative and superlative adjectives must agree in case with the noun they modify, just like positive adjectives.
Using wrong comparison word
- Wrong: Hän on isompi että minä.
- Right: Hän on isompi kuin minä.
- Why: Finnish uses kuin (than) for comparisons, not että (that).
Practice Tips
- Object comparison: Compare items around you: Tämä kirja on paksumpi kuin tuo. Tämä pöytä on isompi kuin tuo. Tämä huone on valoisampi.
- Irregular forms drill: Memorize the irregular comparatives and superlatives as sets: hyvä-parempi-paras, huono-huonompi-huonoin, pitkä-pidempi-pisin.
- Superlative questions: Practice asking superlative questions: Mikä on suurin kaupunki? Kuka on paras pelaaja? Mikä on kaunein maa?
