As an adult, sanya wants to learn spanish and become a spanish teacher. she is having trouble trilling the r and does not sound like a native speaker. what kind of synapse overproduction and pruning process is associated with sanya's difficulty

im not sure of the process, but the r pronunciation of spanish speakers are learned near birth when the language is introduced early in their lives, similar to any other language. This is why some people have accents when speaking a non-native language

i have no clue xdxdxdxdxdxd
