Sorry, yes. I wrote that mess. I'm swedish, we use the same word for both sides of the transaction. "Låna" - very obviously related to the english "loan". It didn't occur to me that there is a directionality to the English term.
No, you’re right. Probably English is not their first language.
some (most?) languages have a single bidirectional word
In Haitian creole, if the main object of the verbe “prete” is a person, it means loan, and the second object says what. If it’s only one non person object, it means borrow.
In Swedish for example, “att låna” is ”to borrow”, and ”att låna ut” is ”to lend” (”to loan out”).
German leihen is loan, while verleihen is lend.
The "ver" is akin to "away", i.e., "loan away" (though this isn't a 1:1 translation and only works for one of the meanings on both sides of the language barrier).
