the word is "Mamihlapinatapei", It describes a look shared by two

people with each wishing that the other will initiate something that
neither one wants to start.
it´s a yaghan or yámana word (yaghán-yaghan is spanish name for the
people took from the Selknam language; and yamana self-naming).
Language is extint as only one speaker survives (a lady who used to
speak ir along with her sister recently late), in Navatino Island,
southern Chile, and language fail to pass to next generation,

Proper spelling: Yahgan, NOT Yaghan. Jess Tauber (mentioned at Paleo-etymology thread) speaks it, a sometimes active member of Synergeo (Bucky Fuller geodesic domes etc.).

New article on Falkland islands settlement, likely by Yahgan canoeists, possibly with friendly foxes that became the wild Falklands wolf.

The enigmatic, now-extinct Falkland Islands wolf had human visitors on the remote archipelago up to 1,070 years ago. The find suggests that Indigenous people could have originally brought the foxlike creatures, also known as the warrah, to the islands.

Scientists have debated how the islands’ only land mammal journeyed to the region: by a long-ago land bridge or with people. But little evidence of a human presence before Europeans arrived in 1690 had been found. Now, traces of ancient fires and
hunting show that Indigenous people arrived on the Falkland Islands centuries prior to Europeans, researchers report October 27 in Science Advances. The Yaghan [sic] people — historically fire-wielding seafarers who kept foxes as companions — may
have been the visitors.

Abrupt spikes in charcoal levels in sediments offer “telltale signs of human arrival” from 1,070 to 620 years ago on New Island, says Kit Hamley, a paleoecologist and archaeologist at the University of Maine in Orono. Those spikes mirror later traces
of Europeans’ fires around 250 years ago.

And massive piles of sea lion and penguin bones imply hunting by humans from 745 to 600 years ago, Hamley says. Before being hunted to extinction by Europeans in 1875, the Falkland Islands wolf (Dusicyon australis) also consumed marine predators such as
sea lions and penguins, nitrogen levels in two warrah bones and one tooth show.

The researchers newly dated that tooth and found it to be from 3,860 years ago. That vastly predates the fire-and-bone-pile evidence, leaving a gap “between when the warrah arrives, and when we can definitively say people were there,” Hamley says.
