destapar

To uncover or take the lid/cap off something literally (destapar una botella, to open a bottle) and, just as commonly, to expose something hidden figuratively — destapar un escándalo, to blow the lid off a scandal. The related noun destape named a whole cultural moment: Argentina's early-1980s explosion of previously censored sexual and cultural content after the return of democracy.

• ¿Puedes destapar el frasco de mermelada? — Can you open the jam jar?
• La investigación destapó una red de corrupción. — The investigation exposed a corruption network.
• El periodista destapó el fraude tras meses de trabajo. — The journalist exposed the fraud after months of work.

Missing the figurative sense entirely — English speakers often default to "uncover" only for physical lids, but destapar un escándalo/una verdad (to expose a scandal/truth) is just as standard and shows up constantly in news headlines.

• politics El Destape — The name given to Argentina's explosive early-1980s social and cultural phenomenon — after the return of democracy, sexual and cultural content previously censored by the military dictatorship flooded film, television, and print; the term derives directly from destapar.
