MSI is a linguistic investigation series that examines one of the most chaotic realities of Brazilian Portuguese: the same idea can appear under many different names, expressions, tones, and social disguises.

Each episode opens a new case file on a suspicious word or expression that seems simple at first, but quickly reveals a network of synonyms, informal meanings, regional uses, emotional tones, and everyday traps for students.

With the atmosphere of CSI, the procedural drama of Law & Order, and a suspicious touch of The X-Files, MSI treats vocabulary like evidence and meaning like a crime scene.

No bodies disappear here.

Only the student’s comprehension.

And MSI is here to recover it before Portuguese files another report.
