Deriving Transitive Verbs with -ntaa / -ntää

In Finnish, you can easily turn an adjective into an active, transitive verb by attaching the suffix -ntaa or -ntää to the adjective's stem.

These derived verbs indicate the action of making something take on the quality of the adjective. They are always transitive, meaning the action is done directly to a target object.

For example, from the adjective vaalea (light), we derive the verb vaalentaa (to lighten). Vowel harmony dictates whether you use the back vowel version (-ntaa) or the front vowel version (-ntää).

Do you want to lighten the hair today?
Haluatko vaalentaa hiuksia tänään?

Adding Contrast with "joskin"

You can express "although" or "even though" using the conjunction joskin. Like other conjunctions, it joins two clauses to add a reservation or contrast to the main point.

Let's look at it in action alongside the verb huonontaa (to worsen, derived from huono).

The hairdresser lightens the hair, although it can worsen their quality.
Kampaaja vaalentaa hiukset, joskin se voi huonontaa niiden laatua.
Shall we darken the shade a little?
Tummennammeko sävyä vähän?
You should cool the yellow shade.
Sinun kannattaa viilentää keltaista sävyä.

Stem Adjustments

When attaching -ntaa / -ntää, the adjective's final vowel sometimes changes (often to an e) or drops entirely to make the word easier to pronounce:

  • syvä (deep) becomes syventää
  • pehmeä (soft) becomes pehmentää
  • ohut (thin) becomes ohentaa
  • paksu (thick) becomes paksuntaa
The dark color deepens your look.
Tumma väri syventää sinun ilmettäsi.
We can soften the bangs, although it requires time.
Voimme pehmentää otsatukkaa, joskin se vaatii aikaa.
I must thin out the thick ends.
Minun pitää ohentaa paksuja latvoja.
This cut thickens thin hair.
Tämä leikkaus paksuntaa ohutta tukkaa.

Transforming Appearance

These verbs are frequently used to describe how a style or choice affects a person's overall appearance or perceived age.

Using the adjectives nuori (young) and vanha (old), we derive the verbs nuorentaa (to make someone look younger) and vanhentaa (to age someone).

Short hair makes you look a lot younger.
Lyhyt tukka nuorentaa sinua todella paljon.
The gray color ages the face, although it is stylish.
Harmaa väri vanhentaa kasvoja, joskin se on tyylikäs.
