Editing Language code (section)

== Difficulties of classification ==
Language code schemes attempt to classify the complex world of human languages, [[dialects]], and [[Variety (linguistics)|variants]]. Most schemes make some compromises between being general and being complete enough to support specific dialects.

For example, [[Spanish language|Spanish]] is spoken in over 20 countries in North America, Central America, the Caribbean, and Europe. Spanish spoken in [[Mexican Spanish|Mexico]] will be slightly different from Spanish spoken in [[Peruvian Spanish|Peru]]. Different regions of Mexico will have slightly different dialects and accents of Spanish.  A language code scheme might group these all as "Spanish" for choosing a keyboard layout, most as "Spanish" for general usage, or separate each dialect to allow region-specific variation.
