Puerto Rico
Puerto Rican Spanish is a Caribbean dialect defined by consistent consonant weakening — final and intervocalic 's' aspirates or drops, intervocalic 'd' disappears, and 'r' in coda position often lateralizes or takes on a uvular quality. Vowels remain strong and open where consonants weaken, giving Boricua speech a distinctive sound profile. Deep cultural and demographic ties with the US mainland have produced extensive English contact, with loanwords absorbed into Spanish grammar using standard Spanish morphological endings and gender assignment.
