From, at, to

since, from (then on) · с

The -⁠sta is the start, and any of the four words after it means from then on. Asti and saakka only mean all the way: after -⁠sta they mean since, after -⁠Vn until. In space too: Vaasasta asti, all the way from Vaasa.

from … to … · с … до …

Both edges at once, with the same endings as a trip: Helsingistä Tampereelle, aamusta iltaan.

look, seem · казаться, выглядеть каким-то

Works like kuulostaa hyvältä. With an object it means show: Näytä kuva!

seem, come across as · казаться, производить впечатление

Works like kuulostaa hyvältä. With -⁠Vn it means affect: vaikuttaa terveyteen.

enjoy · наслаждаться

Works like pitää: pidän kahvista, nautin kahvista. With an object it means have (food or drink): nauttia keittoa.

interested

Interest comes out of something, like liking: pitää sinusta, kiinnostunut sinusta. Crushes and love go into: ihastunut sinuun.

in (the time it takes) · за

How long it takes to get something done. If it doesn’t get done, measure it: Luin kirjaa kaksi päivää. English in also means from now, which is kuluttua.

until, up to · до

The -⁠Vn is the end: something lasts and stops there. For something that happens once, before a point, Finnish says mennessä. Russian до covers both.

by (at the latest) · к

Something happens once, at some point before the deadline. Something that lasts until a point takes asti. Russian к is mennessä, but до can be either.

by (a clock time or a day) · к

With a clock time, -⁠ksi is the time to be there or ready by: Tule kahdeksaksi = Tule kahdeksaan mennessä. Eight o’clock itself, the answer to Moneltako?, is kahdeksalta.

for (a planned length) · на

The length you plan when you set off, arrive or borrow: lähteä, tulla, jäädä, lainata. How it actually went is a measure: Otto oli Singaporessa kaksi vuotta. Russian на makes the same split.

for (how long something hasn’t happened) · уже … не

In a negative sentence, the stretch of not doing it runs up to now, so it points to now: -⁠Vn, the whole phrase. English for and Russian год don’t change between yes and no; Finnish does.

taken with, smitten · влюблённый, увлечённый

Works like rakastunut: rakastunut häneen, ihastunut häneen. Not -⁠sta, which belongs to kiinnostunut (interested).

get to, get into, make it · попасть

Works like mennä: mennä kotiin, päästä kotiin. With an action: pääsen tulemaan, I can make it.

come to mind, come back to someone · вспомниться, прийти на ум

The memory is the subject, as in мне вспомнилось. Shorter: Mieleeni muistui… With yourself as the subject, use muistaa.

in love

Love goes into someone, as in Russian влюблён в: rakastunut häneen. Ihastunut works the same way.

We’ll get back to this!

Palataan asiaan (literally “let’s return to the matter”) is how a work email says “I’ll get back to you on this”. Palata takes the illative: asia becomes asiaan. Palaillaan is the relaxed “catch you later”, with the same light -il- as soitellaan.

Good luck in your new home!

Onnea takes the illative, because the wish goes “into” the new thing. The same frame gives Onnea uuteen työhön! (“Good luck in your new job!”).
