Start With The Marker
Use the code system when you see G, U, R, I, or a numbered dichotomy such as R1 or I2.
CodesModel L Reference
Codes, poles, elements, positions, and derived lenses in one place.
This glossary is designed to sit beside Kimani White's Model L documentation and the TetraTypes Explorer. It keeps codes visible because the codes are part of the learning: R1, I1, R2, I2, and G4 are not decoration, but structural handles.
Use the code system when you see G, U, R, I, or a numbered dichotomy such as R1 or I2.
CodesUse the element glossary when you need the exact name behind Ti(N.), Ne(F.), Se(T.), or any other monadic form.
ElementsUse positions and blocks when you need to know what A1, D2, B3, or Dovetailing means in the cross.
PositionsUse the assignment rules when you need to work out the bracketed marker rather than guess it from subject matter.
RulesPerceiving Elements
T. and F. mark the rational influence on Perceiving elements: objective/detached or subjective/involved.
Judging Elements
N. and S. mark the irrational facility on Judging elements: abstract/conceptual or concrete/embodied.
Code System
The compact code encodes class, family, and level. This is the part of the naming system that makes the terminology memorable rather than arbitrary.
| Marker | Meaning | Use |
|---|---|---|
| OD | Ordinal Dichotomy | Describes intrinsic structural conditions of the functional field. |
| CD | Capacity Dichotomy | Describes how a type uses, accesses, or navigates functions. |
| G | Global | An ordinal state, frame, identity, or concentration condition. |
| U | Universal | An ordinal axis, mode, requisite, or concern. |
| R | Rational | A capacity dichotomy governing the Rational/Judging family dimension. |
| I | Irrational | A capacity dichotomy governing the Irrational/Perceiving family dimension. |
| 1-4 | Depth level | Level 1 is most foundational; Level 4 is the most peripheral attentional layer. |
Notation
Model L notation combines a classical element with a sub-variant marker. The broad element names the information domain. The marker names the mode of engagement.
Perceiving elements, S and N, receive a T. or F. sub-variant. T. indicates an objective, detached, logically influenced mode. F. indicates a subjective, involved, ethically influenced mode.
Judging elements, T and F, receive an N. or S. sub-variant. N. indicates an abstract, conceptual, intuitively influenced mode. S. indicates a concrete, embodied, sensing-influenced mode.
R1 Longitudinal Facing determines the T./F. polarity used by Perceiving elements in foreground/background terms. I1 Latitudinal Facility determines the N./S. polarity used by Judging elements in facile/resistant terms.
Kimani's source terminology uses Preception for the J side of the Jungian faculty split: Logic and Ethics as judgement-making or information-managing faculties. This site also uses Judging as a reader-friendly equivalent.
TIM means Type of Information Metabolism. It is the classical socionics term for a type as a whole: not just a personality label, but a structure for how information is processed and prioritised.
Ti(N.) and Ti(S.) are not two labels for the same thing. They are the same broad element in different monadic modes, and those differences matter in typing and relations.
Sixteen Monadic Elements
The terms below follow the Model L naming system already used across the site. The base type is the type for which the element is A1 Base.

Sixteen Positions
A and D preserve the Model A bridge. B and C are radial positions in the expanded Model L cross.
| Code | Name | Capacity | D/P | Demand | Reading |
|---|---|---|---|---|---|
| A1 | Base | A - Preeminent | 4D / 4P | 0 | The type's most natural leading orientation. |
| A2 | Creative | A - Preeminent | 3D / 3P | 0 | Flexible production in service of the Base. |
| A3 | Ignoring | A - Preeminent | 3D / 1P | -2 | Competent but low-priority background use. |
| A4 | Demonstrative | A - Preeminent | 4D / 2P | -2 | Strong, available, often shown without being central. |
| B1 | Correspondent | B - Auxiliary | 3D / 2P | -1 | Capable liaison to the Base, useful but tiring to sustain. |
| B2 | Collaborative | B - Auxiliary | 2D / 3P | +1 | Visible support that often benefits from feedback or cooperation. |
| B3 | Compensatory | B - Auxiliary | 2D / 3P | +1 | Short-burst compensation that shores up weaker or less central areas. |
| B4 | Instrumental | B - Auxiliary | 3D / 2P | -1 | A reliable tool used in service of favoured ends. |
| C1 | Subsidiary | C - Contributive | 3D / 2P | -1 | Quiet support often subsumed by the Base agenda. |
| C2 | Negligent | C - Contributive | 2D / 3P | +1 | Easier than Vulnerable, but often handled with careless indifference. |
| C3 | Prompting | C - Contributive | 2D / 3P | +1 | Background prompting that can direct access to C4. |
| C4 | Galvanizing | C - Contributive | 3D / 2P | -1 | A background support that can rev up Creative output. |
| D1 | Role | D - Inferior | 2D / 2P | 0 | Socially performed, usable, but effortful and unpreferred. |
| D2 | Vulnerable | D - Inferior | 1D / 1P | 0 | The least equipped and least accessible point. |
| D3 | Suggestive | D - Inferior | 1D / 3P | +2 | Strongly wanted but difficult to generate independently. |
| D4 | Mobilizing | D - Inferior | 2D / 4P | +2 | Energising desire, growth pressure, and response to outside support. |
Demand is priority minus dimensionality. Positive demand marks material the type cares about more than it can easily supply alone; negative demand marks surplus facility that can be used without becoming a central concern.
Blocks
Four blocks preserve Model A names or direct equivalents. Four are radial Model L blocks with no classical Model A equivalent.
| Block | Positions | Classical Anchor | Reading |
|---|---|---|---|
| Leading | A1-A2 | Ego | Strong, primary, overt production: Base and Creative. |
| Trailing | A3-A4 | Id | Strong, ancillary, tacit background competence: Ignoring and Demonstrative. |
| Consultative | B1-B2 | Model L radial | Auxiliary, apparent support in the same broad club territory. |
| Delegative | B3-B4 | Model L radial | Auxiliary, persistent support handled more deliberately. |
| Correlative | C1-C2 | Model L radial | Contributive, apparent background support from the contrasting axis. |
| Supportive | C3-C4 | Model L radial | Contributive, persistent background prompting and galvanising. |
| Diverting | D1-D2 | Super-Ego | Inferior, overt pressure: Role and Vulnerable. |
| Dovetailing | D3-D4 | Super-Id | Inferior, tacit desire: Suggestive and Mobilizing. |
Dichotomy Families
Kimani's Model-L document groups the fifteen codes into eight named families. Each family either supplies a single axis or combines two axes into one of the fourfold lenses used across the Explorer.
| Family | Codes | Derived Lens | Model A Anchor |
|---|---|---|---|
| Parameter | G1 Set Identity / U1 Metabolic Axis | Central / Radial | The valid Model A bridge plus the radial extension. |
| Facet | R1 Longitudinal Facing / I1 Latitudinal Facility | Capacity | Strong / Weak and club small-groups. |
| Vector | G2 Phenomenal State / U2 Modal Engagement | Vergence | Overt / Tacit, also Mental / Vital. |
| Tract | R2 Functional Alignment / I2 Directional Polarity | Current | Primary / Ancillary, also Valued / Unvalued. |
| Perspective | G3 Dispensatory Frame / U3 Compositive Requisite | Ensemble | Necessitating / Supplying, also Accepting / Producing. |
| Complex | R3 Expressive Emphasis / I3 Selective Approach | Array | Governing / Compliant, also Inert / Contact. |
| Orientation | G4 Focal Concentration / U4 Attentional Concern | Interest | Salient / Adjunct / Germane / Tangential; separates Bold / Discreet from Pertinent / Incidental. |
| Purview | R4 Preceptive Domain / I4 Perceptual Sphere | Occupation | Engrossing / Attendant, also Evaluatory / Situational. |
Base Dichotomies
These are the two-pole structural divisions used to read the sixteen-position cross. The code should be learned with the name and poles.
| Code | Name | Poles | Use |
|---|---|---|---|
| U1 | Metabolic Axis | Central / Radial | Separates the Model A bridge from the radial extensions. |
| R1 | Longitudinal Facing | Foreground / Background | Determines outward-facing versus background position facing; also carries the T./F. rational family axis for Perceiving sub-variants. |
| I1 | Latitudinal Facility | Facile / Resistant | Determines ease of processing and the S./N. facility axis for Judging sub-variants. |
| G2 | Phenomenal State | Explicit / Implicit | Distinguishes what is directly legible from what operates more tacitly. |
| U2 | Modal Engagement | Default / Alternate | Distinguishes ordinary mode from contrasting mode. |
| R2 | Functional Alignment | Favored / Menial | Describes whether a position aligns with preferred metabolic functioning or carries less favoured work. |
| I2 | Directional Polarity | Prevalent / Subdued | Describes whether a position stands forward in the pattern or recedes into quieter expression. |
| G3 | Dispensatory Frame | Pivotal / Contingent | Separates anchoring positions from positions more dependent on conditions. |
| U3 | Compositive Requisite | Constitutive / Extrinsic | Separates what belongs to the make-up of a lens from what adds outside support. |
| R3 | Expressive Emphasis | Emphatic / Tentative | Distinguishes more insistent expression from less insistent expression. |
| I3 | Selective Approach | Directive / Conducive | Distinguishes steering the approach from enabling or assisting it. |
| G4 | Focal Concentration | Intensive / Extensive | Describes concentrated depth versus broader distribution of attention. |
| U4 | Attentional Concern | Pertinent / Incidental | Distinguishes direct relevance from adjacent or secondary concern. |
| R4 | Preceptive Domain | Consistent / Variable | Distinguishes steadier domains from more context-variable domains. |
| I4 | Perceptual Sphere | Immersive / Cursory | Distinguishes deep perceptual involvement from lighter contact. |
Assignment Rules
Do not guess the bracketed marker from vibe or subject matter. Derive it from function family plus position property.
| Function Family | Position Property | Rule | Example |
|---|---|---|---|
| Judging: T/F | Facile: A and C | Take I1 directly. | LII I1=N. gives A1 Ti(N.) Intellect. |
| Judging: T/F | Resistant: B and D | Take the opposite of I1. | IEE I1=N. gives D2 Ti(S.) Habitus. |
| Perceiving: S/N | Foreground: A and B | Take R1 directly. | ILE R1=T. gives A1 Ne(T.) Ideation. |
| Perceiving: S/N | Background: C and D | Take the opposite of R1. | LII R1=T. gives D2 Se(F.) Impetus. |
Club assignment and sub-variant assignment are related but not identical tasks. Use the club rule to identify which element families belong in each capacity. Then use the Foreground/Background and Facile/Resistant rules to assign the bracketed monadic marker.
Derived Groups
These groups are generated from combinations of the base dichotomies. They should be read as lenses on the same sixteen positions, not as separate systems.
Preeminent (A), Auxiliary (B), Contributive (C), Inferior (D). The largest regional reading of the cross.
Model A AnchorExpands Strong / Weak and the familiar Model A position regions into the A, B, C, and D capacity map.
Overt, Apparent, Persistent, Tacit. A lens for how directly or indirectly a position appears in experience.
Model A AnchorExpands Mental / Vital and the overt-tacit distinction into four ways a position becomes present or recessed.
Primary, Complementary, Supplementary, Ancillary. A functional flow reading built from alignment and polarity.
Model A AnchorExpands Valued / Unvalued: Primary and Ancillary preserve the central valued-unvalued contrast, while Complementary and Supplementary add the radial readings.
Necessitating, Accepting, Producing, Supplying. A frame for how positions participate in the larger composition.
Model A AnchorExpands Accepting / Producing. The group name Accepting is one radial term here, so read the anchor as the classical dichotomy, not just that one group label.
Governing, Accommodating, Facilitating, Compliant. A lens for expressive emphasis and selective approach.
Model A AnchorExpands Inert / Contact: Governing and Compliant preserve the central contrast, while Accommodating and Facilitating show the radial extension.
Salient, Adjunct, Germane, Tangential. A lens for concentrated versus broad attention and direct versus secondary concern.
Model A AnchorSeparates Bold / Discreet from Pertinent / Incidental, corresponding to Intensive / Extensive and Constructive / Corrective.
Engrossing, Peripheral, Collateral, Attendant. A lens for domain steadiness and perceptual involvement.
Model A AnchorExpands Evaluatory / Situational: Engrossing and Attendant preserve the central contrast, while Peripheral and Collateral map the radial variants.
Interpretive Cautions
F. indicates subjective or involved mode, not a fixed social topic. Ne(F.) can attach to science, art, nature, craft, religion, people, or anything else.
Same broad aspect does not mean same monadic element. Ti(N.) and Ti(S.) are kindred, not identical.
Model A relation names remain useful, but Model L asks where the exact monadic element lands in the other type's cross.
Use the Explorer for verification. If a written interpretation and the cross disagree, return to the code, the position, and the element placement before extending the interpretation.
