Season 7 · Episode 16
The Simpsons
While researching into Jebediah Springfield's past for an essay, Lisa discovers that the town founder wasn't the hero that everyone thinks he was.

The vosotros imperative form of escuchar, which does not belong to everyday Latin American Spanish. Here it is used intentionally as a period marker, imitating the formal call of a colonial-era town crier. Hearing it signals theatrical archaism, not standard usage.
In standard Spanish the correct verb is engrandecer. Engrandar is treated in the episode as a deliberate archaism or error attributed to the fictional historical figure, and its repeated use and defense as an 'acceptable word' is central to the episode's humor. Learners may encounter engrandecer in real contexts.
An archaic exclamation used for comical or theatrical effect, especially in period-costume settings. In modern Latin American Spanish it sounds deliberately old-fashioned or humorous, never serious.
Ruin as an adjective means vile or contemptible, describing a morally base act or person. The exclamation qué ruin expresses moral disgust in a direct but not vulgar way. Common across Latin America in spoken registers.
Archaic vosotros imperative of saber, used in historical or mock-historical written documents. Signals a deliberate imitation of old legal or ecclesiastical language. Not used in modern speech.
