i18n -> l10n -> Multilingual
Internationalization (i18n) is the process of
developing your theme/plugin language, so it can
easily be translated into other languages.
Localization (l10n) describes the subsequent
process of translating an internationalized
theme/plugin.
Multilingual means there are more than one
language in sites.
