Cognate
The word behind the app

cognate

adjective
/หˆkษ’ษก.neษชt/

Sharing a common ancestor; descended from the same root.

PIE *gene- to give birth
Lat cognฤtus of common descent
1590s cognate related by blood
Today cognate sharing a root

English borrowed cognate straight from Latin cognฤtus in the 1590s โ€” com-, "together," plus gnatus, born of the same root as gignere, "to beget." It first named relatives who shared blood. Two centuries later, philologists comparing languages reached for the same word to describe a quieter kinship: English night and German Nacht are cognates not because anyone shares blood, but because both descend from the same Proto-Indo-European parent. The app is named after that second sense.
