In December 2022, the linguist Concepción Company Company gave a lecture at El Colegio Nacional on stereotypes about Mexican Spanish. One is that it is extremely polite. Such stereotypes, she said, “tienen mucho de falso y tienen mucho de cierto también” (have much that is false and much that is true).
On requests, she had data. “Tenemos fórmulas de petición corteses, larguísimas, esto lo he medido” (We have courteous request formulas, very long ones, I have measured this). Mexican speakers use an average of 11 to 12 words to ask for something. Orders are phrased as questions, as in me echas la mano, no seas (give me a hand, go on).
