Questions & Answers about Mam już umówioną wizytę w przychodni na piątek.
Yes. Mam is the 1st person singular of mieć (to have), so it literally means I have.
In Polish, it is very natural to say mam wizytę for I have an appointment. English often uses I have an appointment too, so this part matches quite well.
Also, Polish usually drops the subject pronoun ja (I) because the verb ending already shows who is doing the action:
- mam = I have
- masz = you have
- ma = he/she/it has
So Ja mam już umówioną wizytę... is possible, but ja is usually unnecessary unless you want emphasis.
Już means already.
So:
- Mam już umówioną wizytę = I already have an appointment arranged
- or more naturally: I already have an appointment booked
It often adds the idea that this has been done before now, and there is no need to arrange it anymore.
Its position can vary, but here it sounds very natural after mam:
- Mam już umówioną wizytę
- Już mam umówioną wizytę
Both are possible, though the emphasis changes slightly.
