In the Samogitian dialect of Lithuanian it's spelled "erbata", however the first "a" in modern Lithuanian isn't stressed, so it's very similar. Also in Kashubian (spoken in parts of northern Poland, often considered a dialect of Pomeranian) it is the same as modern Lithuanian.
On the other hand in Sambian Prussian it is "tejs", which is similar to "teja" in modern Lativan. It's interesting how two different forms emerged in the same geographic area.
I recently heard from a Turk that ibrik in Turkish today refers only to the small bucket used for washing oneself in Middle Eastern toilets. For the pot used to brew coffee, they say cezve.
Polish goes its own way.
Heck, why not argue that any “tisane” not made from barley isn’t a real tisane.
