OD&D (White Box) had three alignments (Law, Chaos, Neutrality) and three alignment languages.
The “common tongue” spoken throughout the “continent” is known by most humans. All other creatures and monsters which can speak have their own language, although some (20%) also know the common one. Law, Chaos and Neutrality also have common languages spoken by each respectively. One can attempt to communicate through the common tongue, language particular to a creature class, or one of the divisional languages (law, etc.). While not understanding the language, creatures who speak a divisional tongue will recognize a hostile one and attack. Characters with an Intelligence above 10 may learn additional languages, one language for every point above 10 intelligence factors. Thus, a man with an intelligence level of 15 could speak 7 languages, i.e. the common tongue, his divisional language, and 5 creature languages. Of course, Magic-Users’ spells and some magic items will enable the speaking and understanding of languages.
