Some languages, such as French, are both standardized and stabilized. Though regional variants exist, the differences are minor. Other languages, like Arabic, present significant variations between countries or regions. Most often, adults are comfortable understanding the variants, but it is more difficult for children. For those languages, we have chosen the variant that is most middle-ground, most neutral and spoken by the greatest number of people possible. However, we make special packs for certain languages. We have a Spanish pack that covers the main regional variants of South and Central America.
