B1 Expression Informal

De tapadillo

Secretly, on the sly

Meaning

To do something discreetly or covertly, trying not to be noticed.

🌍

Cultural Background

The phrase is deeply linked to the 'Siglo de Oro' and the social customs of Madrid. It evokes the 'picaresca' tradition where outsmarting authority is seen as a sign of intelligence. While 'de tapadillo' is understood, 'por debajo del agua' is a very common local equivalent, especially for shady business or political deals. Argentines might use 'de cayetano' (slang) or 'a escondidas'. 'De tapadillo' sounds a bit more Peninsular (from Spain) but is perfectly understood in literature and news. In Colombia, 'por debajo de cuerda' is the preferred way to describe secret agreements, though 'de tapadillo' is used in formal writing.
