Finnish has no separate dative case for "to a person" and no preposition for "from a person." Instead it borrows the exterior local cases — the ones that literally mean "on / off / onto a surface" — and repurposes them for people. A person you take something from goes in the ablative -lta/-ltä (the "off / away from" case); a person you give something to goes in the allative -lle (the "onto / to" case). The mental image is that people are open places you approach or leave, never enclosed containers you go inside — which is exactly why the interior cases are wrong here.
The source: ablative -lta/-ltä
When something comes from a person — you ask them, get something from them, borrow, buy, or request from them — that person is the source, and Finnish marks the source with the ablative. English uses "from," or often no preposition at all ("ask the teacher"), which is precisely where learners drop the case.
Kysyn äidiltä, saanko jäädä yöksi kaverin luo.
I'll ask mom if I can stay over at my friend's.
Sain isovanhemmilta rahaa syntymäpäivälahjaksi.
I got money from my grandparents as a birthday present.
Lainasin pakettiauton naapurilta muuttoa varten.
I borrowed a van from the neighbor for the move.
The core source verbs are kysyä (ask), pyytää (request), saada (get / receive), lainata (borrow), and ostaa (buy from) — all with the ablative for the person. Note that kysyä and pyytää often carry a second object too: kysyn sinulta neuvoa ("I ask you for advice") — the person is ablative, the thing requested is partitive.
Pyydän sinulta anteeksi — olin väärässä.
I apologize to you — I was wrong. (lit. I ask forgiveness from you)
The recipient: allative -lle
Flip the direction and you flip the case. When something goes to a person — you give, tell, say, send, show, phone, or offer it to them — that recipient takes the allative. This is Finnish's stand-in for the dative, and it is one of the most frequent uses of -lle in the language.
Annan tämän lahjan sinulle.
I'll give this gift to you.
Kerroin kaiken parhaalle ystävälle.
I told everything to my best friend.
Soita minulle heti, kun pääset perille.
Call me the moment you get there.
The recipient verbs include antaa (give), kertoa (tell), sanoa (say to), lähettää (send), soittaa (phone), näyttää (show), and tarjota (offer). Beware that soittaa is a homonym: soittaa jollekulle = "phone someone" (allative), but soittaa jotakin = "play (an instrument)" (partitive) — soitan pianoa.
The mirror pair: kysyn sinulta / kerron sinulle
The cleanest way to feel the system is to watch the same pronoun flip cases as the direction of the exchange reverses. Information you pull from someone is ablative; information you push to someone is allative.
Kysyn sinulta, ja sitten kerron sinulle vastauksen.
I'll ask you, and then I'll tell you the answer.
Sain viestin pomolta ja vastasin hänelle heti.
I got a message from the boss and replied to him right away.
Note vastata in that last example: the person you reply to is allative (vastasin hänelle), even though vastata takes the illative for a question (vastasin kysymykseen, on the illative verbs page). Reply to a person → allative; answer a question → illative.
The sensory frame: näyttää hyvältä
One striking, idiomatic use of the ablative has nothing to do with people. The perception verbs — näyttää (look), kuulostaa (sound), tuntua (feel), maistua (taste), haista/tuoksua (smell) — take the quality in the ablative. Word for word it is "it looks from good," which is meaningless in English; learn it as a fixed frame: näyttää + adjective in -lta/-ltä.
Tämä ruoka näyttää ja tuoksuu todella hyvältä.
This food looks and smells really good.
Suunnitelma kuulostaa minusta järkevältä.
The plan sounds sensible to me.
Miltä uusi työ tuntuu? — Vähän raskaalta aluksi.
How does the new job feel? — A bit heavy at first.
The question word matches: miltä? ("what does it seem like?") is the ablative of mikä, and the answer echoes it — hyvältä, järkevältä, raskaalta. And notice näyttää itself is now a three-way verb: näyttää jollekulle = "show to someone" (allative), näyttää joltakin = "look like" (ablative).
Interior vs exterior: don't send a person inside
The deepest error English speakers make is routing a person through the interior cases (-sta/-stä elative, -Vn illative) because English "from" and "to" don't distinguish inside from outside. In Finnish a person is exterior. You get something from a person with -lta (not -sta), and you give something to a person with -lle (not -Vn). The full interior/exterior split is on the interior vs exterior page, and the three-way "at / from / to" logic on three-way motion.
Both endings harmonize (äidiltä front, naapurilta back; sinulle / talolle) — except -lle, which never changes, since it has no back-vowel twin to switch to.
Common Mistakes
❌ Kysyn äitiä.
Incorrect — the person you ask is the source, in the ablative: kysyn äidiltä.
✅ Kysyn äidiltä.
I ask mom.
❌ Annan lahjan sinua.
Incorrect — the recipient takes the allative, not a partitive object: sinulle.
✅ Annan lahjan sinulle.
I give the gift to you.
❌ Sain kirjeen isoäidistä.
Incorrect — a person is an exterior source: ablative isoäidiltä, not elative (isoäidistä = 'about grandma').
✅ Sain kirjeen isoäidiltä.
I got a letter from grandma.
❌ Ruoka näyttää hyvä.
Incorrect — perception verbs take the quality in the ablative: näyttää hyvältä.
✅ Ruoka näyttää hyvältä.
The food looks good.
❌ Soitin sinuun eilen.
Incorrect — 'phone someone' is allative: soitin sinulle (soittaa sinuun is not the phoning sense).
✅ Soitin sinulle eilen.
I phoned you yesterday.
Key Takeaways
- A person you take something from = ablative -lta/-ltä: kysyä, pyytää, saada, lainata, ostaa (kysyn sinulta).
- A person you give something to = allative -lle: antaa, kertoa, sanoa, lähettää, soittaa, näyttää (kerron sinulle).
- Direction flips the case on the same word: kysyn sinulta (from) / kerron sinulle (to).
- Perception verbs put the quality in the ablative: näyttää / kuulostaa / tuntua hyvältä.
- People are exterior, not interior: never -sta/-Vn for a person — always -lta/-lle.

- Ablative -lta/-ltä: 'from (off)'A1 — The ablative -lta/-ltä means motion off a surface or away from a place or person — pöydältä, torilta, ystävältä — plus clock times and 'looks/sounds like'.
- Allative -lle: 'onto, to'A1 — The allative -lle (never harmonizes) means motion onto a surface or, crucially, to a recipient — pöydälle, torille, annan sen äidille, soitan sinulle.
- Verb + Case: RectionB1 — Finnish verbs lexically fix the case of their complement — rakastan sinua, pidän kahvista, uskon Jumalaan — and it rarely matches the English preposition. Learn the case with the verb.
- Interior vs Exterior: -ssa vs -llaA2 — Finnish has six local cases in a 3×2 grid — interior (in/out-of/into) vs exterior (on/off/onto) — and the choice hinges on whether a place is enclosed or open.
- The Three-Way System: in / into / out ofB1 — Each Finnish locative series is a motion triad — static 'where', goal 'to where', source 'from where' — and your verb must match the direction it names.
