A look shared between two people, each wishing that the other would initiate something that both desire but that neither wants to begin.

From the Yaghan language of Tierra del Fuego, spoken by the indigenous people of the southernmost tip of South America.

Listed in the Guinness World Records as the most succinct word in the world, capturing a complex shared experience in a single term.

The Yaghan language had fewer than a dozen fluent native speakers remaining by the early twenty-first century, making it critically endangered.

The word contains seven morphemes and is built on the root mapi, which in Yaghan refers specifically to a desire felt but unspoken between two people of equal social standing.
