Questions & Answers about Έσπασε ένα πλευρό.
Έσπασε is the 3rd person singular aorist of σπάζω (to break).
So grammatically it means he/she/it broke or it got broken, depending on context. The aorist is the normal Greek tense for a single completed action in the past.
That έ- is the past augment, a very common feature in Greek past-tense forms.
For many verbs, Greek adds this extra sound at the beginning in past forms:
- σπάζω → present
- έσπασα / έσπασε → past
So the beginning of the word helps signal that the action happened in the past.
