Source register

Language sources and status

Source transparency matters because a plausible translation is not automatically pedagogically sound, and a publicly readable word list is not automatically licensed for republication.

Reference	How it informed the build	Republication status
Turkish Textbook: Most Common Words	Concept reference for high-frequency vocabulary. The app now also includes a separate 1,104-entry development file supplied by the project owner.	The supplied file is included as development content, but its provenance, reuse rights and frequency methodology still need confirmation before a branded “top 1,000” claim.
Yaşar Esendal Kuzucu, The Delights of Learning Turkish	Pedagogical inspiration for the sequence dialogue → vocabulary → grammar explanation → exercise, and for beginner themes including restaurant language, word order and cases.	No book passage, exercise set or dialogue is reproduced as app content. The field missions use newly written text and a different interaction structure.

What is original in this build

• All Command Sprint commands, answer layouts, explanations and boss sequences.
• The Café, B202 Supermarket, Kadıköy opinion and apartment-viewing scenes, production challenges and applied grammar panels.
• The Lingo League creatures, Turkish-named move system, tournament structure and battle artwork.
• The Midnight Courier encounters, choices, upgrades, dialogue and original visual-novel game system.
• Game progression, scoring, content schemas and local mastery system.
• Learning guides, privacy disclosure and methodology text.

What is not yet certified

• No claim that the supplied list’s alphabetical IDs are a verified frequency order.
• No qualified-editor sign-off across every Turkish sentence.
• No licensed audio or pronunciation corpus.
• No third-party CEFR accreditation.

Editorial release gate

Before public educational marketing, a qualified Turkish reviewer should check every displayed sentence for grammar, idiom, register and accepted variants; corrections should be recorded in a content changelog. The project should also retain the vocabulary dataset licence, corpus version, selection method and update date before marketing the rank path as frequency-based.
