Linguistic Complexity Index (Full)

Restore Objective Absolute Complexity: Measuring structural units, rules, and irregularities.

I. Phonology & Tone

Phoneme Count Total unique consonants + vowels.

Syllable Density (1-5) How many consonants can cluster together?

1: CV only (Basic) 2: CVC (Standard) 3: CCVC (Clusters) 4: CCCVCC (Heavy clusters) 5: Massive (e.g. CCCCVCCCC)

Tone System (1-5) Complexity of pitch distinctions.

1: Non-tonal 2: Pitch-accent 3: Simple tone (2-3 levels) 4: Complex (4+ tones) 5: Tone Sandhi (Tones change tones)

II. Noun & Pronoun Elaboration

Noun Cases

Noun Classes / Genders

Grammatical Number Hierarchy (1-5) How many quantity categories are mandatory?

1: Nonexistent (No plural marking) 2: Singular / Plural 3: Singular / Dual / Plural 4: Trial or Paucal (Small groups) 5: Complex (e.g. Inclusive/Exclusive duals)

Person Distinctions (1-5) Mandatory pronoun categories.

1: I, You, He/She (Basic) 2: Inclusive/Exclusive "We" 3: Clusivity + Honorific levels 4: Gender-split in all persons 5: Direct-Inverse/Animacy splits

III. Verbal & Morphological Depth

TAM (Tense/Aspect/Mood) Number of distinct required verb categories.

Fusion Intensity (1-5) How blended are the morphemes?

1: Isolating (1:1 mapping) 2: Basic Agglutination 3: Deep Agglutination 4: Fusional (Blended meanings) 5: Extreme Fusion/Inflection

Agreement Scope (1-5) What must the verb track?

1: No agreement 2: Subject only 3: Subject + Object 4: Polypersonal (3+ args) 5: Noun Class Agreement across sentence

IV. Syntax & Irregularity

Alignment Type (1-5) Grammatical logic (Nom-Acc vs Erg-Abs).

1: Consistent Nom-Acc 2: Ergative features 3: Fully Ergative-Absolutive 4: Split-Ergativity 5: Tripartite / Active-Stative

Irregularity Density (1-5) How many exceptions defy the rules?

1: Perfectly Regular 2: Few high-freq exceptions 3: Moderate (dozens) 4: Large lists of exceptions 5: Systemic Suppletion (Roots change)
