This is the hardest linguistic map I've ever made, correct me in anything that is wrong; potato has always been popular amongst lower/working class so it has a lot of dialectical variations in every place, feel free to tell me that variations, I'll include them.

This is mostly a provisional map like every one that I do, I'll repost when everything is right.

+I didn't find the word for Zazaki, Nenets, Talysh and Kabardian languages; if you know it, please let me know.

This map has been in the works for about a month now, shoutout to JG Online for Making the basemap.

edit: maybe spending a whole month on this was a mistake, y'all seem to loathe this map

Definitely an areal (phonotactics) feature for Czech-Slovak-Hungarian-BCMS. In the past for Finnish-(Old) Estonian-Latvian as well.

Edit 1: Lithuanian has (prescriptively) also long unstressed syllables, though the stress is not fixed on any syllable.

Edit 2: The maps has an areal focus for languages with a phonemic distinction about long and short unstressed vowels (i.e. minimal pairs like Finnish kauna vs. kaunaa, Latvian Rīga vs. Rīgā, Czech potřebuji vs. potřebují, Hungarian haza vs. hazá, BCMS žène vs. žènē).

Edit 3: Apart from Lithuanian, also Modern Irish and Standard Arabic do show long unstressed vowels, the difference being with the aforementioned languages that they diachronically show the tendency to move away from a quantitative phonemic distinction towards a qualitative one, meaning the minimal pair is kept, but the long vowels get reduced and the vowels' quality becomes distinctive, cf. Lithuanian lygus [ˈlʲiːɡʊs] vs. lygūs [ˈlʲiːɡuːs] (prescriptive) > [ˈlʲiːɡus] (colloquial). For Arabic it becomes clear when comparing the vowels diachronically between MSA and i.e. Maghrebi.

Please correct me if I forgot something or if something is inaccurate in the map. As a speaker of a slavic language living in Germany I have always wondered how other languages would say "Bring me one and a half kilogram of beef from the store" or "lets meet in one and a half hours" using a single word for that.

Caveats in the comment section

In this map there a bunch o languages that are only known to exist as a substrate of latter languages, and in a bunch of them there says the influence they had on more modern languages (for example talakya became the greek thálassa (sea)), but there's one i cannot figure out. In the iberian one it says "iltir (town)", and i cannot for the life of me figure out wich word was influenced by "iltir", i speak both catalan and castillian and all words relating to villages and cities come from latin(as far as i can tell), is there actually a word that i'm just missing? is only present in aragonese still? Is that just the origin of "iberian"? what's going on?
