Learn Italian: Questa capienza non basta per la logistica. - This capacity is not enough for the logistics.

In this sentence, the entity that needs the capacity isn't a person, so there is no indirect object pronoun like mi (to me) or gli (to him/them). The grammatical subject is simply Questa capienza (This capacity), which directly governs the verb basta. The purpose is then just added on with the prepositional phrase per la logistica (for the logistics).

Could I say alla logistica instead of per la logistica, since bastare usually takes an indirect object?

While you will often see bastare a (to be enough for) when referring to people or conscious entities, using per emphasizes the purpose or function. Here, per la logistica means "for the purposes of logistics". Both structures are valid, but per is highly natural when talking about a process or activity rather than a recipient.

Does capienza translate to any kind of "capacity"?

Capienza specifically refers to physical capacity, volume, or holding space (like the capacity of a warehouse, a stadium, or a hard drive). If you meant "capacity" in the sense of a person's mental ability, skills, or legal capacity, you would use the word capacità instead.

In English, "logistics" ends in an 's' and looks plural. Why is it (singular) in Italian?
