Questions & Answers about Minä laitan avaimen takin taskuun, etten unohda sitä.
Finnish normally does not require subject pronouns, because the verb ending already shows the person.
- Minä laitan = I put
- laitan already tells us it’s 1st person singular.
So both of these are correct and mean the same thing in neutral context:
- Minä laitan avaimen takin taskuun…
- Laitan avaimen takin taskuun…
Using minä often adds emphasis on I:
- Minä laitan avaimen takin taskuun, en sinä.
I will put the key in the coat pocket, not you.
In the example sentence, Minä is not strictly necessary; it just makes the subject explicit and a bit more emphatic or careful-sounding.
