Questions & Answers about Diagnosta już czeka.
Because in Polish, some masculine nouns for people end in -a. Diagnosta is one of them.
So even though it looks like many feminine nouns, it is typically treated as masculine in grammar:
- ten diagnosta = this diagnostician / this male diagnostician
- dobry diagnosta = a good diagnostician
- Diagnosta czekał = The diagnostician was waiting
A learner often expects -a to mean feminine, but Polish has a small group of masculine-person nouns like this.
It is in the nominative case because it is the subject of the sentence — the person doing the action.
So in Diagnosta już czeka, the structure is basically:
- Diagnosta = subject
- już = already
- czeka = is waiting / waits
Polish does not have articles like English the and a/an.
So diagnosta can mean:
- the diagnostician
- a diagnostician
Which one sounds best depends on the context. Polish usually leaves that to the situation, not to a separate word.
