has become ambiguous in use.

If you said, let’s bring stadium seats to the next football game, you’d think it’s coming next. Without one in between.

next
/nekst/
adjective
1.(of a time or season) coming immediately after the time of writing or speaking.

By that definition it’s the 13th. The one immediately after speaking. But colloquially “next” Wednesday has changed to mean “not this one, but the following”, but only in some contexts. It’s the opposite of what you’d mean if you said “next week” (which would mean the week immediately following). So it’s become a somewhat ambiguous word.

We could use another word in English for this idea of “not this one, but the one following it.” That word has already been proposed as “oxt” and is gaining traction slowly.
