Welcome to the Kalob Language Project! Kalob is a highly structured artificial language (engelang) designed around the principles of absolute grammatical clarity and unambiguous word formation.

Kalob is a modern revival, refinement, and expansion of the Blue Language (Bolak), originally published in 1899 by Léon Bollack. Bollack was a visionary Parisian merchant who studied all of the auxlangs of the time and sought to build a logical, highly accessible language from the ground up.

Today, Kalob continues in that exact same spirit. This project aims to polish and modernize Bollack's ambitious 19th-century architecture for the modern era. We have smoothed out the exceptions and inconsistencies of the original framework while preserving its brilliant core mechanics.

• Unambiguous Word Shapes: In Kalob, you can identify the exact grammatical function of a word just by looking at its structure. The language strictly divides its vocabulary into grammatical Shortwords (1 to 4 letters) and content-based Longwords (3 or more letters).
• The 7-Vowel Engine: Kalob utilizes an expanded 7-vowel system where vowels do more than just make sound—they act as grammatical indicators. Alongside a word's final consonant, the word's final vowel dictates it's tense, case, and part of speech.
• Systematic Derivation: Through a strict system of prefixes and suffixes, base root concepts can be reliably transformed into nouns, verbs, adjectives, and adverbs without relying on rote memorization of arbitrary vocabulary.
• Modernized Mechanics: Kalob updates Bolak for the 21st century by introducing a tripartite pronoun system (Animate, Inanimate, Abstract), a reduced approach to "Staffwords" (unattached grammatical markers), and dedicated structural rules for distinguishing between physical and virtual/digital concepts.
• Modernized Phonotactics: Kalob updates Bolak's phonotactics for the modern mouth and ears by eliminating consonant clusters that cause anaptyxis and expanding the scope of Bollack's hard-to-soft rule to nearly the entire lexicon. Due to the introduction of the central vowels, some careful considerations were made to ensure that certain word shapes don't get misheard as central vowels.

Whether you are a conlang enthusiast, a fan of logical systems, or just curious about the history of the Blue Language, we welcome you to explore the grammar, vocabulary, and tools we are building.
