The universal taxi

I was listening to the radio this morning and they were talking about linguistics. I feel very conflicted about this because I love hearing real, proper linguistics on the radio! It's so rare! but the linguist in question has expressed anti-trans attitudes in the recent past and so I can't call myself a fan. But there we go; they at least weren't discussing such issues so they didn't express them in the course of this conversation.

They were talking about demonstratives, this and that. It was a nice discussion, lots of information, and fun facts about proximal and distal demonstratives (this here vs that there) and how these change in context, and also how many languages have a three-way system with a medium-distance and a far-distance one.

And finally they talked about how pronouns are universal: all languages have them. This is indeed super cool, and basically indicates that they are a Very Important and Useful language feature. Any language that didn't have them for some reason would likely innovate them pretty sharpish, and home signs include them, for instance.

Then someone wrote in to say that 'Interestingly, one word that is universal is 'taxi''. This is interesting, but it's not the same thing. Taxi is 'universal' because it's been borrowed into lots of languages. I'd actually be surprised if it's truly universal in the sense that every single language has this word. There are presumably a few where the concept hasn't been needed and lots more where in fact there's a different word meaning 'private car and driver hired for single journeys', or whatever it is that taxi means. A quick google looks like in quite a lot of languages familiar to English speakers, the word for 'taxi' is something like taxi, which does give an impression of universality from this vantage point. And the 'universal' part is the specific form of the word ('taxi'), with a certain meaning.

Pronouns are universal in a different way. The words are not the same in every language (me, your, we, etc). They haven't been borrowed. There is a lot of historical relatedness, to be sure; it's no coincidence that we looks like German wir. But the very fact that there are pronouns is what's universal. This is fundamentally more interesting than that a particular word has been borrowed a lot. (By the way, here is a study that says that the most universal word is 'huh'.)
