Questions & Answers about Πότισε το φυτό λιγάκι.
Here it is being used as a command: Water the plant a little.
But this is a very good question, because πότισε can also be the 3rd person singular aorist form meaning he/she/it watered. In an isolated written sentence, Greek can sometimes be ambiguous like that. Normally, context and intonation make it clear.
So:
- Πότισε το φυτό λιγάκι. = Water the plant a little.
- In another context, the same words could mean He watered the plant a little.
Πότισε is the 2nd person singular aorist imperative active of ποτίζω (to water).
That means:
- 2nd person singular = you are talking to one person
- imperative = it is a command / instruction
- aorist = it presents the action as one complete action
So Πότισε is the kind of form you use when telling one person to do something once, as a single act.
