There are many variations in Spanish dialect.
In New Mexico, a relatively pure form of sixteenth and seventeenth-century Spanish has been preserved from the days before the region was conquered by the United States.
Many Chicanos of Texas and California speak Pachuco, a slang that includes Mexican expressions and English-derived terms. The fast-paced Cuban dialect has been called “Spanish in overdrive.”
Usage varies too: some Latin Americans say vos, others hi, to mean a singular, familiar “you.”
