Burmese - Mon since 13th century
Kambaata - Wolaytta Steadily increasing since the mid-nineties.
Langi - Alagwa Present day
Papapana - Rotokas I don’t know.
Maltese - Sicilian (modern) 1400 - 1800. 2004-2021 (membership of the EU) The densest period of time for contact between Malta and Sicily was from 1050 to around 1550, because political, social and economic ties were practically exclusive. From 1550 onwards such contacts with Italy increased, and ties with the UK began in 1800 but became strong from about 1850 and are strongest today. However, statistics and testimonies for the Sicilian period are scarce, with the result that most of my responses to the questionnaire concern the present time period (roughly the last decades) when contact with Sicily is still ongoing, albeit in a much wider international framework. As regards language, contact with Sicilian died out with the coming of the Knights of St John who introduced Italian, both as an official and a spoken language for the educated classes. Moreover, today the Sicilian dialect is never spoken with foreigners by the Sicilians themselves.
Maltese - Sicilian (historical) 1400–1800. As with other domains, from approx. 1800 onwards contact has been in Italian.
Kwoma - Manambu Around 1820 to 1950, when intertribal warfare in this region came to an end
Korandje - North African Arabic After about 1980
FLNA-NLNA Intensive contact with Neighbour increased drastically during the second Country A civil war (approx, 1983-2004), which ravaged the Focus area. Many people had to flee their homeland and therefore had to acquire at least some Neighbour (the main Country A vehicular) in order to make themselves understood. Around that time, independently from the war, there was also an increasing social pressure among Focus speakers to acquire Macro-Neighbour, the main language used in schools and in administrative / official settings in the Country A.
Zaza - Turkish See KN 2 [QID: DKN0a]
Yuhup - Macuna 1980-2020
Temoaya Otomi - Mexican Spanish Around 1950
Mawng - Kunbarlang 1600-1800
Santali - Bengali Since independence of India in 1947.
Bade - Manga Kanuri For the past 500 years
Muak Sa-aak - Tau Lü From 50 years ago up to the present
Sibe - Uighur 1920s-present ca.100 years
Toba - Spanish From 1950 to the present, when the largest number of Toba people migrated to big cities.
Western Toba - Wichí From 1930 to 1960.
Paluai - Tok Pisin The present day.
Nen - Idi As per my other answers
Burarra - Yolngu Matha Arguably, the contemporary era has provided the most opportunities for interaction in the labour domain. Shared labour is likely to have characterised pre-colonial group dynamics (e.g. the production of material culture, subsistence labour), and to some extent these practices still continue alongside newer forms of labour made possible in larger urban communities – in this case at Maningrida particularly where many Burarra and YM people live and work every day.
South Saami - NorwegianSwedish Probably modern times.
Kupwar Marathi - Kupwar Kannada My guess is that the largest number of people had the most opportunities for interaction in the labour domain before the sale of farm lands in Kupwar began (approx. 1920s onwards) The shift away from caste-based economic relations must admittedly have been gradual, spanning over about seventy years from 1920s until the 1990s.
Aleut - Eyak cf. above: slavery existed for at least 2000-3000 years along Pacific Coast, and the most direct and intense contact would have occurred prior to 800 BP
Wutun - Bonan This is quite difficult to assess on the basis of information we have today, but it is likely that the most intensive contact occurred between the establishment of Ming Dynasty (in early 14th century) and the establishment of Republic of China (in early 20th century).
