Constructed language (conlang)

Worldbuilding, lore & consistency
Fantasy
Science fiction

A conlang isn't invented for decoration: it structures a people's thought.

Definition

A conlang can range from a dozen evocative words ("naming language") to a complete grammar with phonology, writing, and diachronic evolution. The choice depends on the role it plays in the story, not on a Tolkien fantasy.

What it's for

A constructed language is a collective characterization tool: it shows how a people carves up the world (sense of time, kinship, the sacred). It also anchors worldbuilding: one well-chosen word can replace a page of description. But it has a reader cost — overuse = unreadable murmur.

Variants by genre

  • Tolkien-style: complete language with history (Quenya, Sindarin) — high benchmark.
  • Naming language: just enough for coherent names (Le Guin, Earthsea).
  • Philosophical conlang: a language that changes thought (Chiang, Story of Your Life; Orwell, Newspeak).
  • Alien conlang: non-human phonology (Watts, parts of Vinge).
  • Futuristic SF conlang: post-collapse creole (Hoban, Riddley Walker).
  • Modern TV conlang: Dothraki and Valyrian (Peterson, Game of Thrones), Na'vi (Avatar).
  • Implicit conlang: no invented words but warped syntax (Damasio, La Horde du Contrevent).

Common pitfalls

  • Invented words ungloss-able, reader lost by page 2.
  • Conlang contradicting its own phonology (decorative apostrophes).
  • Overuse: everything is in conlang, nothing is readable.
  • Conlang with no associated culture: sounds without people.
  • Conlang that "speaks English in costume" (same syntax, swapped vocabulary).

Examples

  • J. R. R. Tolkien — Quenya and Sindarin, starting point of the whole mythology.
  • Ursula K. Le Guin — Kesh (Always Coming Home), full conlang for a future culture.
  • Marc Okrand — Klingon, a TV conlang that became self-teaching.
  • David J. Peterson — Dothraki, Valyrian (GoT), Na'vi (Avatar).
  • Russell Hoban — Riddley Walker: post-apocalyptic English, read phonetically.
  • Anthony Burgess — A Clockwork Orange: Nadsat, Slavic-English slang.
  • George Orwell — 1984: Newspeak, a political conlang.

Writing tips

  • Set the lexical budget before writing: 20–60 invented words for a standard novel, 100–150 for dense fantasy. Beyond, the reader drops; below, the conlang doesn't exist.
  • Phonology first, lexicon second: pick 4–6 signature consonants and 3–4 recurring vowels. Every new word passes through this filter, otherwise the language sounds glued.
  • First-occurrence test: every invented word must be glossable from immediate context (an action, an object, a nearby synonym). Zero footnotes, zero appendix.
  • Let the language voice its culture: at least one word should name a notion untranslatable in English (a grammatical tense, a social status, a taboo). That's what separates a true conlang from decoration.

Revision checklist

  • Can each conlang word be glossed in context without a footnote?
  • Is the phonology consistent (one sound, one spelling)?
  • Does the language say something about the people who speak it?
  • Does the conlang stay a spice, never the main course?
