saber
/saˈbeɾ/ · A1 · verb
to know, to understand
📚 From Latin sapere, to taste, be wise: same root as savvy and sapient
Latin sapere meant to taste, then to have good sense. It gave Spanish saber (which still also means to taste: sabe a limón) and English savvy, sapient, savor. Sound hook: a savvy person sabe.
