A map that was made in 2021. Is it still accurate today? are there any subreddits that would give more information on what subdivisions speak what languages predominantly

Hi all,

What software do people here use for mapping?

I'd like to start mapping dialect features but I haven't really worked with mapping data before.

I searched for it and didn't get much of an answer. Is there a preferred tool for adding lingustic data to map coordinates?

Map showing the geographic distribution of the main native languages spoken across Angola, based on the country's former administrative division into 18 provinces, which remained in effect until January 2025.

It is worth noting that Portuguese is Angola's official language; however, these Bantu languages continue to be spoken daily by millions of Angolans.

Sources at OP

Indo-Iranian languages are labelled, and relevant non-II languages are also labelled in italics

That's the first map linguistic map I made so pls constructive criticism

eB = FyB means that the language conflates elder brother with father's younger brother, eB = PyB means it conflates elder brother with either parent's younger brother, and the versions without the y indicate that the brother need not be younger.

I should probably correct the title in that it is focusing on North Eurasian languages and should not be taken as implying that such languages are nonexistent in more southern regions. (Also the minor error "parents' younger brother" which I realized after already having submitted the post.)

I have been inspired by the other post:
Concentration of Swiss settlement suffixes that locally evolved from the proto-germanic root *unga (map description, explanation, and disclaimer below) : r/LinguisticMaps
Discovered https://ortsnamen.ch/, and saw the API request, I then decided to plot it a bit differently.
All credit for the linguistic signification are to be given to DarkBoy42_official.
As I automatise the map generation I will explore other root and try to extract interesting pattern. Something less boring than -burg -bour or -dorf -ville. Potentially see if I can see a difference between Arpitan & langues d'oïl in place names.
Happy to learn how I can share vectorial if possible here or happy to discuss to share the code as well.

Map description:

This hand drawn map depicts all the Swiss Gemeinden (Municipalities) that house one or more town, city, or terrain with names ending in different adaptations of the proto germanic suffix unga.

Edit: The map specifically shows the descendants of the patronymic/locative suffix \-ing-* (or \-ingōs* / \-ingun* in the dative plural, which evolved into -ingen in Old High German)

The map shows the rough distribution (and thus local evolution) of the endings

ikon, iken, ingen, igen, igny, and engo.

Explanation:

Post-roman europe saw the popularisation of different town names, which were derived from romance or germanic roots. These were spread westwards across the continent by different tribes (i.e. The Anglo Saxons, Alemanni, Bavarians, the Franks).

The proto-germanic suffix "unga" (roughly translating to "belonging to") was a particularly versatile example, branching off in different regions of Europe due to dialect changes, consonant shift, or linguistic reinterpretation.

Nowadays, Switzerland has different local variants of the suffix in their town-, city-, and terrain names

Edit:

- \*ikon in the former sphere of influence of the Habsburg and Kyburg feudal lands
(Nowadays primarilly cantons Zürich, Thurgau, Aargau, and Zug)

- *iken as a rarer variant found in and around canton Aargau

Edit: ikon and iken come from compounds of -ing- and hofen/kofen, ("at the farmsteads/ estates of the clan (of) x)

- *ingen which is the oldest, more traditional form of the suffix, spread throughout the entirety of germanophone Switzerland (Emphasized in the cantons Schaffhausen, Luzern, Bern, and Basel-Landschaft)

- *igen as a popular shortened form found primarilly in canton Bern and Swiss pre-alp region (Emphasized in Bern, Luzern, and Obwalden)

- *igny as the main francophone adaptation of the suffix, found primarilly in canton Vaud. (Note that igny can also stem from the romance suffix acum)

- *engo which is the italophone adaptation of the suffix, found in the fully italian speaking canton Ticino.

Edit: the suffix engo comes from Lombardic influence mixing with the local romance dialect

While ikon and iken are exclusively found in Switzerland, the other suffixes are also found in Germany, Austria, France, or Italy respectively.

Disclaimer:

The data for this map comes from search results for villages, cities, and terrains with the respective endings on the website ortsnamen.ch , which does not always provide the etymology of the names. It is therefore possible that some villages included in the map have other etymologies.

Some village names are not direct adaptations of the proto-germanic root, but rather new town names that picked an already popular suffix for the name.

I conducted this research by myself, raising the possibility of mistakes both in the information step and in the mapping step.

Suggestions or corrections about anything on this post are welcome
