εξαιτίας
"Because of" or "due to."
The term 'εξαιτίας' ('because of') is utilized to indicate the reason the activity (not going for a picnic) was not completed, due to the external factor of rain.
Δεν πήγαμε για πικνίκ εξαιτίας της βροχής.
We didn’t go for a picnic because of the rain.
Here, 'εξαιτίας' is used to justify the action of leaving early, which resulted from the presence of noise.
Οι άνθρωποι έφυγαν νωρίτερα από το πάρτι εξαιτίας του θορύβου.
People left the party earlier because of the noise.
This instance shows 'εξαιτίας' indicating the cause (technical problems) leading to the delay of the project.
