Romero (2015) and Hill & Hill (1986)

As Romero (2015:45–48) describes, people from Chiquimula hold beliefs about the purity of their variety of K’ichee’. How are these beliefs the same as or different from the purity code that Hill & Hill (1986) argue is operative in the Mexicano-speaking communities of the Malinche? Be as specific as you can in your answer, using illustrative examples and as many details as you can from both the Romero (2015) and Hill & Hill (1986) readings.
