Here's one that might be useful.
Who can explain the differences between aqui and aca, and alli and alla?
I know I missed the accents - I'm lucky to have a computer.
I don't know how they are used in the Dominican, but in Texas we use them as such.
aqu?: If you call someone that is in another room and want him to come to the room that you are in we would say: "?Ven aqu?!
ac?: If your child has done something bad and you want to scold them: ?Ven ac?!
all?: If you are pointing something/ someone out that you can see: La chica all?...
all?: If you are refering to something/ someone that is not visible: No te vayas pa'lla.
I could very well be wrong about everything... if so please correct me so that I can adjust my fire
