💡 Grammar Points
Vowel Change in the Present
In the present tense, the 'o' in the verb's root changes to 'ue' (o > ue) for most people, including 'ellos/ellas/ustedes' ('muestran'). This sound change happens when the emphasis falls on that part of the word.
❌ Common Pitfalls
Forgetting the Stem Change
Mistake: "Ellos *mostran* la colección."
Correction: Ellos *muestran* la colección. Remember that the 'o' turns into 'ue' in the present tense for this form.
⭐ Usage Tips
Use with Reflexive Pronouns
The verb can be used reflexively as 'mostrarse' (to show oneself or to reveal one's feelings): 'Ellos se muestran preocupados' (They show themselves to be worried).

When people provide evidence or results, they muestran (prove) their findings.
muestran(verb)
