Vanheta ("to grow old / age") is the reference verb for Type 6, the rarest and most semantically uniform class: verbs in -eta/-etä that mean "become more X". They are inchoative — they express a gradual change of state — and most derive straight from an adjective: vanha ("old") → vanheta ("grow old"), kylmä ("cold") → kylmetä ("get cold"), pimeä ("dark") → pimetä ("get dark"). The signature is an expansion: the -eta infinitive opens into an -ene- present stem, vanheta → vanhene-, just as paeta → pakenen and lämmetä → lämpenen. The participle contracts it back to vanhennut. Vanheta itself has no gradation, but several members of the type do (see inverse gradation and paeta below).
Present and past (indicative)
Stem vanhene-. The past drops the -e- before -i-: vanheni.
| Person | Present | Past (imperfect) |
|---|---|---|
| minä | vanhenen | vanhenin |
| sinä | vanhenet | vanhenit |
| hän | vanhenee | vanheni |
| me | vanhenemme | vanhenimme |
| te | vanhenette | vanhenitte |
| he | vanhenevat | vanhenivat |
| negative | en vanhene | en vanhennut / emme vanhenneet |
Vanhenen, mutta yritän pysyä uteliaana.
I'm growing older, but I try to stay curious.
Koira vanhenee nopeammin kuin ihminen.

Isoisä vanheni silmissä sen vaikean vuoden aikana.

Perfect and pluperfect
Both use olla plus the participle vanhennut (plural vanhenneet), which contracts the -ne- stem.
| Person | Perfect | Pluperfect |
|---|---|---|
| minä | olen vanhennut | olin vanhennut |
| hän | on vanhennut | oli vanhennut |
| me | olemme vanhenneet | olimme vanhenneet |
| he | ovat vanhenneet | olivat vanhenneet |
| negative | en ole vanhennut | en ollut vanhennut |
Olen vanhennut vuoden, mutta en ole hitustakaan viisastunut.
I've grown a year older, but I haven't gotten a bit wiser.
Conditional, potential, imperative
The conditional drops the -e- before -isi-: vanhenisi. The potential (formal/literary) builds on the infinitive stem vanhet-: vanhennee. The imperative vanhene! exists but is rare for meaning reasons — one seldom commands someone to age; the plural and jussive forms build on vanhet-.
| Person | Conditional | Potential (formal) | Imperative |
|---|---|---|---|
| minä | vanhenisin | vanhennen | — |
| sinä | vanhenisit | vanhennet | vanhene! |
| hän | vanhenisi | vanhennee | vanhetkoon (formal) |
| me | vanhenisimme | vanhennemme | vanhetkaamme (formal) |
| te | vanhenisitte | vanhennette | vanhetkaa |
| he | vanhenisivat | vanhennevat | vanhetkoot (formal) |
| negative | en vanhenisi | en vanhenne | älä vanhene |
The perfect conditional is olisin vanhennut ("I would have grown old").

Who wouldn't grow old, given enough time.
Hyvä ystävyys ei vanhene, vaikka näkisi toisiaan harvoin.

Passive
Type 6 verbs are intransitive change-of-state verbs, so the passive is impersonal and fairly rare — but it exists and is fully regular, built on vanhet-: present vanhetaan, past vanhettiin.
| Form | Affirmative | Negative |
|---|---|---|
| present | vanhetaan | ei vanheta |
| past | vanhettiin | ei vanhettu |
| perfect | on vanhettu | ei ole vanhettu |
| conditional | vanhettaisiin | ei vanhettaisi |
| potential (formal) | vanhettaneen | ei vanhettane |
Suomessa vanhetaan nykyään terveempinä kuin ennen.

The rest of the family (and gradation)
Type 6 is small, so it is worth seeing several members at once. Note that some show inverse gradation — the weak grade in the infinitive, the strong in the -ene- stem. The clearest is paeta ("flee"), where a k appears out of nowhere: pae- → pakene-.
| Infinitive | Present (minä) | Past participle | Meaning |
|---|---|---|---|
| vanheta | vanhenen | vanhennut | grow old |
| paeta | pakenen | paennut | flee (k↔∅ gradation) |
| lämmetä | lämpenen | lämmennyt | warm up (mp↔mm) |
| pimetä | pimenen | pimennyt | grow dark |
| kylmetä | kylmenen | kylmennyt | get cold |

Common Mistakes
❌ Ihminen vanheaa hitaammin nykyään.
Incorrect — the stem carries -ne-: the 3rd person is vanhenee, not *vanheaa.
✅ Ihminen vanhenee hitaammin nykyään.
People age more slowly these days.
❌ Olen vanhenut kymmenen vuotta tuossa työssä.
Incorrect — the participle doubles the n: vanhennut, not *vanhenut.
✅ Olen vanhennut kymmenen vuotta tuossa työssä.
I have aged ten years in that job.
❌ Ulkona pimeää nopeasti tähän aikaan vuodesta.
Incorrect — this needs the verb pimetä: pimenee, not the adjective pimeä.
✅ Ulkona pimenee nopeasti tähän aikaan vuodesta.
It gets dark quickly outside at this time of year.
❌ Vanki paenee vankilasta.
Incorrect — paeta takes the strong-grade k in the -ene- stem: pakenee, not *paenee.
✅ Vanki pakenee vankilasta.
The prisoner is escaping from the prison.
Key Takeaways
- Present stem vanhene-: the -eta infinitive expands to -ene- (vanhenen, like paeta → pakenen).
- Past vanheni, conditional vanhenisi drop the -e- before -i-.
- Participle vanhennut (pl. vanhenneet) and passive vanhetaan / vanhettiin build on vanhet-.
- Meaning is inchoative — "become more X" — and many members are built from adjectives; watch for inverse gradation (paeta → pakenen).
