Demuestran

Demuestran is the third-person plural present indicative form of the Spanish verb demostrar. It corresponds to "they demonstrate" or, in formal address, "you (plural) demonstrate." The verb demonstrates, in general usage, the act of showing something to be true or evident, or presenting evidence that supports a claim. It also appears in mathematical and logical contexts with the sense of proving a theorem or proposition.

Etymology and classification: demostrar comes from Latin demonstrare, meaning to point out or show. In Spanish, it is a stem-changing verb: in the present tense its stem changes from demostrar to demuest- in all forms except nosotros and vosotros, which retain the regular endings. The present indicative forms include demuestro, demuestras, demuestra, demostramos, demostráis, demuestran.

Usage notes: Demuestran is used to indicate that observations, data, or arguments provide support for a conclusion. Examples: "Los resultados demuestran la hipótesis." "Las pruebas demuestran su inocencia." In mathematics, demostrar is used in the sense of proving a theorem: "El teorema se demuestra con una demostración." The verb is common in academic, scientific, legal, and everyday language.
