To make mutually dear or beloved; to endear to each other.
From co- (together) + endear (make dear, from dear + -en). This verb describes making people affectionate or dear to one another through shared experience.
Shared hardships and adventures are what coendear people most—think of soldiers or teammates who bond through struggle, which is why 'coendear' captures something 'love' and 'friendship' don't quite express.
