You don't really want "aig" here. It's not a physical thing and it can't be passed between people, so it can't be "aig" someone.IainDonnchaidh wrote:I hijacked this thread aig clarsach.
If you consider it to be like a book, it would be "le Clarsach" ("le" is used like "by" for attributing something to an author, but it's also "with" when linking a radio or TV program to a presenter).
Alternatively, you may need to use a genitive construction if you consider it like an idea or a party. (But I don't remember the rule for putting people's names into the genitive, and even if I did I'm not sure whether Clarsach's a he or a she. And even if I knew that, I'm not sure what I'd be supposed to do if Clarsach was the opposite gender from the gender of the dictionary word "clarsach". It's a minefield, so I'm not going to go there!!!)
This whole internet thing's so new, I doubt the natives have reached a consensus on how to deal with internet threads.
I suppose the best analogy would be "comhradh". If you were hijacking someone's conversation, how would you say that? Anyone?
