• ZG_2_05 — Across civilizations, certain languages have been elevated above the ordinary functions of communication to the status of sacred or liturgical languages — vehicles believed to possess special…
• ZG_2_06 — Historical linguistics is the scientific study of how languages change over time, how they are related to each other, and how they can be grouped into language families descended from common…
• ZG_2_07 — A dead language is one that no longer has any native speakers — no community transmits it to children as a first language through normal intergenerational communication.

• ZG_2_13 — Dialectology — the systematic study of regional linguistic variation — investigates how languages differ from place to place, mapping the geographical distribution of pronunciation, vocabulary,…
• ZG_2_14 — Historical pragmatics investigates how language use in context — speech acts, politeness strategies, discourse organization, implicature, and interpersonal meaning — has changed over time.
