Questions & Answers about Kun saan vaikean tehtävän valmiiksi, tunnen oloni itsevarmaksi.

What does kun mean in this sentence, and how does it affect the word order?

Kun is a conjunction meaning “when” (sometimes “as” or “since,” depending on context).

In this sentence:

• Kun saan vaikean tehtävän valmiiksi = When I finish a difficult task
• tunnen oloni itsevarmaksi = I feel confident.

Word order:

• Finnish does not invert subject and verb after kun like English often does after some conjunctions.
• So you simply have: kun + subject + verb + rest
  
  • kun
    • saan (I get) + vaikean tehtävän valmiiksi (the difficult task finished)

The comma separates the kun‑clause (subordinate clause) from the main clause, which is standard in writing.

Why is it “saan … valmiiksi” and not just a single verb like lopetan or valmistun?

Saada X valmiiksi is a very common Finnish expression meaning “to get X finished / to complete X.”

• saan = I get (from saada, “to get, to receive, to be allowed to”)
• valmiiksi = into a finished/ready state (see more on the ending below)

So literally: “When I get a difficult task into a finished state, I feel confident.”
Natural English: “When I finish a difficult task, I feel confident.”

You could use other verbs:

• Kun lopetan vaikean tehtävän, … – When I stop/finish a difficult task, …
• Kun suoritan vaikean tehtävän, … – When I complete a difficult task, …

…but saada tehtävä valmiiksi is idiomatic, neutral, and very common.
