The language of an institution
A government may publish a decree in one or several languages, a school may teach a language that pupils do not speak at home, and a religious institution may maintain an older textual norm. These practices shape access and prestige, but an official document records the institution first. Ask whether the surviving item is a law, a copy of a law, an exercise, a private letter or a ritual book. The same language name can denote very different kinds of use in these settings.
Policy is not identical to practice. A rule can exist without consistent enforcement; a local school can differ from national policy; a bilingual curriculum can be taught unequally. To test the effect of a policy, compare records before and after it in matched places and genres, and seek accounts of how pupils and families used languages. A date on a decree should not be relabeled as the date a population changed speech.
Literacy is a separate skill
Knowing how to speak a language and knowing how to read a script are different capacities. A scribe may write on behalf of a speaker. A community may be orally fluent while most surviving writing uses another language, as the Library of Congress study describes for Vietnamese beside learned Chinese. The emergence of a written vernacular changes the archive available to us, but it does not prove that the vernacular began at that moment.
A script can also cross language boundaries. Cuneiform was adapted from Sumerian to Akkadian and other languages; a reader trained on its sign lists could work with the same graphic system while learning distinct languages. DCCLT’s educational tablets show this teaching process directly. Use the object’s language and its signs as separate catalog fields.
Language planning and identity
Modern campaigns can establish teaching materials, spellings, media and public services. UNESCO’s Quechua interview describes activism for bilingual education and recognition. These are community and institutional histories, not merely a count of school textbooks. In ancient study, apparent standardization may instead come from a narrow scribal tradition whose members selected one variety for copying. Where the evidence does not reveal community participation, avoid assigning motives.
Practice: select a multilingual inscription or school tablet. Identify its commissioner, probable readers, languages, scripts, physical setting and date. Then write separate sentences for what it proves about policy, literacy, and speech. Cross out any sentence for which the object provides no evidence.
