Example: Someone is born in the United States of Mexican parents and speaks both English and Spanish fluently since birth. They then go abroad to France to study French. Will they speak French with an English accent or a Spanish accent, or will they speak it with an accent in between English and Spanish? (By English and Spanish, I mean the English and Spanish languages, not the accents of England and Spain. Obviously in this case this individual would have an American English and a Mexican Spanish accent in their two languages).
