Plateletter

Plateletter is a fictional writing system used in speculative fiction and world-building contexts to describe inscriptions on plates and similar mediums. The term combines plate, referring to the medium, and letter, a reference to the sign units that comprise the script. In most depictions, Plateletter functions as a hybrid script that merges logographic elements with phonetic cues.

In-world usage: In the stories, Plateletter is carved or incised on ceramic plates and metal tablets that circulate among merchants, priests, and scholars. Its logographic core conveys concepts such as ownership, season, or ritual status, while its alphabetic strokes indicate pronunciation or grammatical relations.

Structure and decipherment: Plateletter glyphs typically consist of a central circular plate motif with radiating or attached strokes that denote phonemes or affixes. The writing direction varies by text but is commonly top-to-bottom or left-to-right in inscriptions. A published Plateletter Key within the fiction provides a mapping from glyphs to sounds and meanings, enabling scholars to interpret the inscriptions.

Historical context in fiction: The scripts originate in Bronze Age culture known as the Platewrights, with evidence found on domestic plates and ceremonial votives. Over centuries, Plateletter spread through trade networks, leaving inscriptions that form the basis for modern in-world paleography.

Reception and usage outside fiction: Plateletter is widely discussed in world-building and linguistics forums as an example of a hybrid writing system; it is used to illustrate the concept of artifacts telling multilingual histories. It has no real-world usage beyond fiction.
