Questions & Answers about Vyplnil jsem formulář a podepsal ho.
No. Vyplnil is one verb form, from the verb vyplnit meaning to fill out / complete.
It only starts with a capital V because it is the first word in the sentence. It is not the formal pronoun Vy.
So:
- Vyplnil = filled out / completed
- Vy = you (formal or plural)
They just happen to look similar at the beginning.
Czech often leaves out subject pronouns when they are clear from the verb.
Here, jsem tells you this is first person singular: I.
So:
- Vyplnil jsem formulář = I filled out the form
You could add já:
- Já jsem vyplnil formulář
But that usually adds emphasis, contrast, or clarity. In normal neutral sentences, Czech often omits já.
