Questions & Answers about Non abbiamo finito il progetto per colpa della tua pigrizia.
Why use per colpa della here instead of a causa della?
Why did di become della in this sentence?
The compound preposition is per colpa di. Because it is followed by la tua pigrizia, the preposition di combines with the definite article la to form the combined word della.
Why is there an article before tua pigrizia anyway?
In English we just say "your laziness", but Italian generally requires a definite article before a possessive word like tua. The main exception is for singular close family members (like tua sorella), but for abstract nouns like laziness, the article is always required.
