The Spanish verb mostrar means to show. A similar verb in Spanish is enseñar (to teach or show). The following are some examples of how the verb mostrar can be used:

  • Mostrar can mean to make something visible, to demonstrate or exhibit: El vendedor muestra sus productos (The salesman shows his products).
  • Mostrar can be used to talk about teaching someone how to do something: Ella me mostró cómo hacer la tarea (She showed me how to do the homework).
  • Mostrar can also mean to express an emotion, such as to show anger: Carlos mostró su enojo durante la discusión (Carlos showed his anger during the argument).

Another interesting detail is that from the verb mostrar we get the noun muestra, which means a sample or sometimes a sign, as in una muestra de sangre (a blood sample) or una muestra de esperanza (a sign of hope).

Mostrar is a stem-changing -ar verb. That means that in some of its conjugations, there is a change in the verb stem. In this case, the vowel "o" changes to "ue" when in a stressed syllable, as in yo muestro (I show). Other similar stem-changing verbs are sonar, probar, and contar.
