Questions & Answers about Ona szepcze mi do ucha, że pociąg zaraz odjeżdża.
That’s true: Polish often leaves out subject pronouns when the verb already makes the subject clear.
- szepcze already means he/she/it whispers
- so Szepcze mi do ucha... would also be a perfectly natural sentence
Including ona usually adds one of these effects:
- emphasis: She is the one whispering
- contrast: she, not someone else
- clarity: if the context needs the subject spelled out
So ona is not required here, but it is grammatical and natural.
szepcze is the:
- 3rd person singular
- present tense
- of the verb szeptać = to whisper
So:
- ja szepczę = I whisper
- ty szepczesz = you whisper
- on/ona/ono szepcze = he/she/it whispers
In this sentence, it matches ona.
