This is the 12309th most frequent Spanish word.
levantan
"Levantan" means "they lift" or "they raise."
Here, 'levantan' is used reflexively, indicating the action of getting up performed by the subject on themselves.
Los estudiantes se levantan temprano para ir a la escuela.
The students get up early to go to school.
In this usage, 'levantan' is not reflexive and means raising an object—in this case, the hands.
Levantan las manos cuando quieren hacer una pregunta.
They raise their hands when they want to ask a question.
Here, 'levantan' is again reflexive but is used metaphorically to suggest taking a stance or position in opposition.
