Questions & Answers about Dnes jdu pěšky ke škole.
In Czech the subject pronoun (já = I) is usually omitted, because the verb ending already tells you who the subject is.
- jdu clearly marks 1st person singular (I go / I am going).
- Adding já is only needed for:
- emphasis: Já dnes jdu pěšky ke škole. (I am walking today, not someone else.)
- contrast: Já jdu pěšky, on jede autobusem.
So:
- Dnes jdu pěšky ke škole. – neutral, natural Czech.
- Já dnes jdu pěšky ke škole. – sounds a bit emphasized.
