English has one main way to single out a constituent for emphasis: the cleft, "it was Matti that called." Finnish has that construction too — Se oli Matti, joka soitti — but it uses it far more sparingly, because two lighter tools usually do the job first: free word order (fronting the focused element) and the focus clitics -han / -pä. Understanding when to deploy the heavy se-cleft, and when a bare fronting is the natural choice, is a genuine C2 skill: the cleft is marked, and over-using it makes your Finnish read as translated-from-English.
The se-cleft: se + olla + relative clause
The dedicated cleft frames the focused element as the predicate of olla, then attaches a relative clause with joka:
Se oli Matti, joka soitti eilen illalla.
It was Matti who called yesterday evening.
Se oli tämä kirja, jonka halusin, ei tuo.
It was this book that I wanted, not that one.
Two things surprise English speakers here. First, the copula agrees with the focused person, not with se: "it was me" is Se olin minä, "it was you" is Se olit sinä.
Se olin minä, joka rikkoi ikkunan — anteeksi.
It was me who broke the window — sorry.
Se olit sinä, joka aloitti koko riidan.
You're the one who started the whole argument.
Second — and this is the classic trap — the relative pronoun takes the case its role demands inside the relative clause, independently of the focused noun. If the focused noun is the subject of the relative verb, use joka; if it's a total object, jonka; if a partial object, jota; and so on.
| Role in relative clause | Pronoun | Example |
|---|---|---|
| subject | joka | Se oli Matti, joka soitti. |
| total object | jonka | Se oli Matti, jonka näin. |
| partial object | jota | Se oli kahvi, jota kaipasin. |
| recipient (allative) | jolle | Se oli Matti, jolle soitin. |
Se oli Liisa, jonka näin torilla, en Anna.
It was Liisa whom I saw at the market, not Anna.
Fronting: the unmarked way to focus
Because Finnish marks grammatical roles with case, not position, you can move a constituent to the front of the clause for contrastive focus without any cleft scaffolding at all. This is the default, unmarked focus strategy — lighter and far more common than the se-cleft.
| Neutral | Fronted (focus) |
|---|---|
| Matti teki sen. — "Matti did it." | Matti sen teki. — "MATTI did it." |
| Tarkoitin sinua. — "I meant you." | Sinua minä tarkoitin. — "It was YOU I meant." |
Matti sen teki, ei kukaan muu.
Matti did it — no one else.
Sinua minä tarkoitin, en häntä.
It was you I meant, not him.
Where English needs the cleft ("it was you that I meant") to shift focus onto the object, Finnish just moves sinua to the front and lets word order carry the emphasis. This is the single most useful insight for an English speaker: before you build a se-cleft, ask whether a simple fronting says the same thing more naturally. In the great majority of cases, it does.
Helsingistä minä sen kirjan ostin, en Tampereelta.
It was in Helsinki that I bought the book, not in Tampere.
Clitics and particles as focus markers
Finnish can also glue a focus marker onto the fronted word. The clitics -hän / -han and -pä / -pa both attach to the focused element and add a shade of "as we both know" (-hän) or triumphant pointing (-pä):
Sinähän sen ehdotit — älä nyt syytä minua!
You're the one who suggested it — don't blame me now!
Sinäpä sen tiedät paremmin kuin kukaan.
You of all people know it best.
The particle -hän is treated in depth on the -han clitic page. Alongside the clitics, the adverbs juuri ("exactly, precisely") and vasta ("only, not until") narrow focus onto a specific element or moment:
Juuri sitä minä tarkoitin.
That's exactly what I meant.
Vasta silloin tajusin, mitä oli tapahtunut.
Only then did I realise what had happened.
These pack the emphatic work into a single word, sparing you the whole cleft apparatus — which is exactly why fluent Finnish leans on them. For the bigger picture of what goes first and why, see topic and focus and fronting for emphasis.
When the cleft is the right choice
The se-cleft earns its weight when you need an unmistakably emphatic, almost adversarial focus — correcting a mistaken assumption, assigning responsibility, or setting up a strong contrast in careful or written style (neutral → formal). In quick speech, fronting or a clitic almost always wins.
Common Mistakes
❌ Se oli Matti, jota soitti.
Incorrect — Matti is the subject of soitti, so the pronoun must be joka.
✅ Se oli Matti, joka soitti.
It was Matti who called.
❌ Se oli minä, joka rikkoi ikkunan.
Incorrect — the copula agrees with the focused person: Se olin minä.
✅ Se olin minä, joka rikkoi ikkunan.
It was me who broke the window.
❌ Se oli sinua, jonka näin.
Incorrect — the cleft predicate is nominative (sinä); the object case belongs on the relative pronoun (jonka).
✅ Se olit sinä, jonka näin.
It was you whom I saw.
❌ Se oli sinä, jota minä tarkoitin.
Overuse — natural Finnish just fronts the object: Sinua minä tarkoitin.
✅ Sinua minä tarkoitin.
It was you I meant.
❌ Oli Matti joka soitti.
Incorrect — the cleft needs the dummy subject se: Se oli Matti, joka soitti.
✅ Se oli Matti, joka soitti.
It was Matti who called.
Key Takeaways
- The dedicated cleft is se + olla + relative clause: Se oli Matti, joka soitti.
- The copula agrees with the focused person: Se olin minä, Se olit sinä.
- The relative pronoun takes the case its own clause demands — joka / jonka / jota / jolle — regardless of the focused noun.
- The unmarked, everyday focus strategy is fronting (Sinua minä tarkoitin) or a clitic / particle (sinähän, juuri sitä), not the cleft.
- Reserve the se-cleft for strong, contrastive emphasis; over-using it sounds heavy and translated.
