"The poor brain-eating aliens. And also the owners of the brains."

"I agree on both counts!"

"Am I correct in thinking there's no way to reach either set of people?"

"I have no idea how I got here and no knowledge of how to get back, but that doesn't mean a way doesn't exist, just that I don't have access to it."

"Hm. Well, I'd really like to know how but I don't see any obvious way to make progress on the question. You were turned into a human first, right? And spent some time being a human on your planet? Does the planet have a name?"

"I know its name in the brain-eating-alien language that I can't pronounce anymore but it just means approximately 'third planet from local star'. I don't know its name in any other languages."

"What's the closest you can get to pronouncing it?"

"Hmmm..."

She frowns a small frown of concentration, makes some sounds with her mouth that frankly do not sound like they belong in any language at all, then shakes her head. "Sorry, I don't really think there's enough overlap between the way brain-eating aliens naturally speak and the ways humans can speak to make this work. I could make up a name for it? I could... use the word for 'third' in the human language I'm familiar with from that planet? That would be 'Sarn'."

"I guess we can declare Sarn to be its English name, being as we are English speakers."

"That seems reasonable!"

"It's not a very clever name but our planet's name just means 'dirt' so I guess it's consistent!"

"I think there are occasions where simplicity is more important than cleverness and this might be one of them!"

"I don't think clever names are harder to remember or anything. But it doesn't really matter."
