Learn Hardcore Finnish: Kyllä, minä tulen kohta.

It’s an emphatic or confirming “yes.” With Kyllä, you’re not just stating the fact that you’ll come soon, you’re explicitly confirming or assuring it—like “Yes, I will indeed come soon.” Without it, Minä tulen kohta is a neutral statement; with Kyllä, it answers a yes/no prompt or stresses your commitment.

Is Kyllä the same as Joo?

Both can mean “yes,” but they differ in tone. Joo is casual, like “yeah.” Kyllä is firmer/more formal or emphatic and can also function as a sentence particle to add emphasis inside a sentence (e.g., Minä tulen kyllä). Other affirmatives: Totta kai (“of course”), Ilman muuta (“by all means”).

Do I need the comma after Kyllä?

If Kyllä stands as an interjection (“Yes,”) followed by a clause, a comma is natural: Kyllä, minä tulen kohta. If kyllä functions as a sentence adverb (no pause), you usually skip the comma: Kyllä minä tulen kohta. Both are common; it depends on whether you intend a pause after “yes.”

Do I have to say minä, or can I drop it?

You can drop it: Kyllä tulen kohta or Tulen kohta are perfectly fine. Finnish verb endings show the subject, so the pronoun is optional. Including minä adds emphasis or contrast (often “I, as opposed to someone else”) and is common in speech.
