sinceridad
/sinθeɾiˈdad/ · B2 · noun · f
earnestness
🤝 sinceridad = sincere + -dad (-ity): the state of being sincere
Latin sincerus meant clean or pure. A popular but false story says it comes from sine cera, without wax, meaning honey with no wax added. Either way, sinceridad is the pure, unadulterated truth. The -dad ending matches English -ity.
