I. PHONOLOGY & WORD CONSTRUCTION

Rule 1: Phonetic Inventory

Fiwo uses a fixed, closed set of phonemes chosen for global prevalence and perceptual distinctness.

Consonants:

p, b, t, d, k, g, m, n, nn, f, v, s, z, c,y, h, x, q, l, r, w, j

Vowels:

i, e, a, o, u, ii

Orthography:

• Words are written exactly as they are pronounced.
• Each phoneme maps to exactly one written form.
• Proper nouns may be imported from other languages and adapted to the closest Fiwo phonemes if necessary.
• No capitalization is used except for proper nouns.

Rule 2: Syllable and Word Shape

• Every word must begin with a consonant and end with a single vowel. Words may only have more vowels at the end if they are derived, see rule 4.
• Up to 3 consecutive consonants and 2 consecutive vowels may occur internally.
• Only grammar particles may violate internal structure constraints if explicitly listed.

II. MORPHOLOGICAL TRANSPARENCY (THE DATA LAYER)

Rule 3: Functional Vowels (Word Categories)

The final vowel of a word unambiguously determines its category, with the exception of grammar words.

A word's category is always recoverable without context.

Rule 4: Derivation (Category Shifting)

Fiwo allows words to change their grammatical category (part of speech) to fit new contexts without losing their root meaning.

The Mechanism: Appending

To change a word's category, append the Functional Vowel of the target category to the end of the existing word.

• Do not remove or replace the original vowel.
• The final character of the word always dictates its current grammatical category.

4.1 Derivation Formulas

Modifier or noun to verb - add i.

jotze (clean) → jotzei(cleaning). batu (Food) → batui (To eat).

Noun or verb to modifier - add e.

do (day) → doe (daily). beati ( to close) → beatie (closed).

Modifer to noun - addo .

loge (able) → logeo (the ability)

Verb to noun - add a.

pauli (to feel) → paulia (the feeling)

Preposition to noun - add o.

hemii(near) → hemiio(the nearby/surroundings)

Preposition to modifier - add e.

hemii(near) → hemiie ( Nearly/closely (regards to position))

4.2 Constraints & Edge Cases

1. Preposition Constraint: Prepositions (words ending in *-`ii`*) cannot be converted into Verbs. They function strictly as logic gates and cannot be "performed."
2. Sequential Derivation: Derivation may be applied twice for highly specific nuances, provided the final vowel correctly signals the final category.
   • Example: *batu* (Food) → *batui* (To eat) → *batzuia* (The act of eating).
3. Pronunciation: Derived vowels are fully pronounced.
   • *batui* is pronounced /ba-tu-i/.

III. SYNTAX & STRUCTURE (THE LOGIC LAYER)

Rule 5: Basic Word Order

Fiwo uses a fixed default order:

Subject – Verb – Object (SVO)

Example: mi lo batui te mito. (I eat meat)

An alternative passive-like structure is allowed:

Object – Verb – Subject (OVS)

This requires the particle bii.

Example: te mito lo batui bii mi ( The meat was eaten by me.)

This specific preposition can triggers the passive interpretation.

Rule 6: Marker System (Hierarchy & Reference)

Fiwo separates lexical certainty (word endings) from structural certainty (markers). Markers are structural particles that determine the role, scope, and hierarchy of the words that follow them.

6.1 Predicate Markers (The Verb Hierarchy)

Fiwo strictly distinguishes between the Main Clause (the assertion) and Subordinate Clauses (background information or description).

A. The Main Predicate — lo

• Function: Marks the start of the main verb phrase of the sentence.
• Constraint: Exactly one lo is allowed per sentence. It defines the root of the parse tree.
• Structure: Subject + lo + (Tense) + Verb...

B. The Subordinate Predicate — ki

• Function: Marks the start of a dependent verb phrase. It allows verbal information to function as a modifier (relative clause) without competing with the main predicate.
• Constraint: A kiclause cannot contain lo.
• Negation: ne applies locally within a kiclause (e.g., "The dog that did not bite me").
• Structure: Noun + ki + (Tense) + Verb + (Object)

Example: mifu ki pa nidai te mi lo mzi.(The dog [that bit me] is sleeping.)

6.2 Object Marker (te)

• Function: Marks the start of the Direct Object.
• Logic: Everything following te belongs to the object phrase unless structurally regrouped (via pii).
• Necessity: This prevents verbs inside complex noun phrases from being misinterpreted as new predicates.

Structure: Verb + te + Object Phrase

6.3 Clause Deictics (si / ta)

These markers allow the speaker to refer to entire events or clauses as if they were nouns.

A. Proximal Clause Deictic — si

• Function: Refers to the current or immediately preceding clause ("This event").
• Usage: Can be used to turn a clause into a specific modifier definition.
  • Example: mifu si ki... ("This dog, which...")

B. Distal Clause Deictic — ta

• Function: Refers to a previously established or conceptually distant clause ("That event").
• Usage: Used to comment on a previous statement.
  • Example: ta lo ci retse. ("That [previous event] is dangerous.")

6.4 Usage Modes

• Strict Mode:
  • lo and te are mandatory.
  • Required for: Complex logic, technical writing, AI communication, and sentences with multiple ki clauses.
  • Result: Ambiguity is structurally impossible.
• Fluid Mode:
  • Markers may be omitted when the structure is simple (SVO) and context is obvious.
  • Result: Natural, expressive speech.

6.5 Pronoun Animacy (Agency vs. Object)

Fiwo strictly distinguishes between entities with Agency (da) and entities without Agency (za).

• Animate (da): Applies to humans, higher animals, or personified entities capable of making choices or having intent (Agency).
• Inanimate (za): Applies to objects, concepts, plants, simple life forms, or machines, regardless of movement or complexity.

Note: An AI (xioco) may be referred to as da if the speaker attributes agency/personhood to it, otherwise it is za.

Rule 7: Structural Grouping (pii)

The particle pii acts exclusively as a structural grouping operator (functionally identical to an open parenthesis ( in mathematics).

• It does not imply ownership, origin, or material.
• It signals that the entire phrase following it forms a single modifier unit that applies to the word before it.

Usage:

• Linear (No pii): foisa nnofae je lande
  • Logic: ((foisa + nnofae) + lande)
  • Meaning: The [small bird-houses]. (Subject to left-associativity).
• Grouped (With pii): foisa pii nnofa je lande
  • Logic: foisa + (nnofa + lande)
  • Meaning: The house of [small birds]. (The house relates to the group "small birds").

Note: To express "The bird's house" (Ownership), do not use pii. Use the specific preposition rii (Owned by).

Rule 8: Logical Negation (ne)

The particle ne is a closed-class structural operator used to encode logical negation. It does not describe qualities (like "bad" or "empty") and acts only on the syntax of the sentence.

1. Default Scope (Predicate Negation)

When used in a clause, ne negates the main action.

It must appear after the marker/tense and immediately before the verb.

• Structure: Subject + lo + (tense) + ne + Verb
• Example: mi lo pa ne cali. (I did not move.)

2. Specific Scope (Group Negation)

ne can negate a specific phrase if that phrase is grouped using pii.

It must appear immediately before pii.

• Structure: ... + ne + pii + (Grouped Phrase)
• Example: mi lo cali ne pii zii jura.
  • Literal: I moved [NOT (to the city)].
  • Meaning: I moved, but not to the city (I went somewhere else).

3. Pragmatic Response

When used alone as a sentence, ne. functions as the standard refusal ("No").

4. Constraints

• Never a Modifier: You cannot say hanu ne for "not a box." (Use hanu de + ne + verb).
• Never combined: Do not combine with modifier endings (e).

Rule 9: Modification & Definiteness

Modifiers always follow the word they modify. Fiwo distinguishes between Subjective Modification (Qualities) and Objective Modification (Relations).

1. General Modification (Suffix -e)

Use the -e ending for subjective qualities, colors, emotions, or general associations (vague "vibes").

• Example: hanu gudue (Metallic box / Metal-ish box).
  • Implication: It looks like metal, or is related to metal, but might be plastic paint.

2. Relational Modification (Prepositions)

Use Relational Prepositions for precise, logical descriptions. This eliminates ambiguity.

• Material: Use dii (Made of).
  • hanu dii gudu (Box made of metal).
• Shape/Geometry: Use lii (Shaped like).
  • hanu lii mazo (Box shaped like a tree).
• Composition: Use nii (Part of).
  • mfuka nii mi (Hand that is part of me / My physical hand).
• Nature/Essence: Use fazii (Nature of).
  • movu fazii nauca (Person with the nature of a friend / Friendly person).

3. Definiteness

Nouns are definite ("the") by default. Indefinite meaning ("a/some") is added with the modifier de.

• mazo (The tree)
• mazo de (A tree)

IV. TIME, LOGIC, & QUANTIFICATION

Rule 10: Tense & Aspect

Tense markers appear after lo and before the verb. Only one tense/aspect marker may appear per clause.

Example:

• mi lo pa cali (I moved)
• mi lo fu cali (I will move)
• mi lo du cali (I am moving )

Rule 11: Quantity & Comparison

Quantity and comparison are expressed using modifiers.

Rule 12: Numbers & Intensity

• Numbers are spoken as digit sequences.
  • Example: 156 = raza raja reso (One-Five-Six)
  • Example: 20 = ratso lta (Two-Zero)
• A number before a noun specifies quantity.
  • Example: reso hanu. = six containers
• Numbers 1–5 acting as modifiers, indicate intensity.
  • Example: kiiteqi ricae (3) = Like mildly; kiiteqi rajae (5) = Like intensely.

V. PRAGMATICS & DISCOURSE

Rule 13: Mood Tags & Punctuation

A Fiwo sentence may begin with a Mood Tag.

Mood Tags explicitly encode the speaker's communicative intent or tone, information that is normally conveyed through body language, facial expression, or vocal intonation in face-to-face speech but is often lost in written text.

Mood Tags apply to the entire sentence and must appear as the first character, before any words.

If no Mood Tag is present, the sentence is interpreted as neutral / declarative by default.

Punctuation Rules

• Punctuation marks (., ,, " ") function as in standard written languages.
• Capitalization is not used, except optionally for proper nouns.
• Mood Tags are not punctuation and do not replace sentence-final marker, thus all sentences must end in a period.

Design Note

Mood Tags increase clarity in text-based communication by making intent explicit, improving both human understanding and machine interpretation without relying on inference.

The core grammar contains no exceptions; modes affect enforcement, not structure.

Rule 14: Closed-Class Grammar (Structural Integrity)

Grammar / Miscellaneous words in Fiwo form a closed class.

They exist solely to encode structure, logic, scope, or sentence control, not real-world meaning.

• Grammar words must not describe entities, qualities, states, degrees, time, or uncertainty (with the exception of Pronouns, which serve as pointers to entities).
• Grammar words must not answer what, who, where, when, how, or why(except for Interrogatives like wu, wa, we which act as placeholders).
• Grammar words cannot be replaced by a noun, verb, modifier, or preposition.

New grammar particles may only be introduced if they:

1. encode syntactic or logical structure, and
2. do not carry independent semantic content.

This rule prevents semantic drift, preserves morphological transparency, and ensures the grammar layer remains stable and predictable for both humans and machines.

Rule 15: Deterministic Parsing (Single-Tree Requirement)

Any valid Fiwo sentence in Strict Mode must produce exactly one possible syntactic parse tree.

This means:

• only one main predicate per clause,
• only one valid object scope,
• unambiguous modifier attachment,
• no interpretation based on context, pragmatics, or speaker intent.

This requirement is enforced through:

• fixed functional vowels (word categories),
• fixed word order (SVO),
• mandatory structural markers (lo, te, pii) in Strict Mode.

If a sentence allows more than one valid structural interpretation, it is invalid in Strict Mode and must be rewritten using markers or grouping particles. Only structurally complete sentences are considered valid Fiwo.

This rule guarantees lossless, machine-safe communication and prevents ambiguity from scaling as sentence complexity increases.
