# Batch 173 Process Log: Body-Part Lexical Expansion

## Scope

Rule 131 is a 50-row, hand-authored body-part lexical expansion after the Rule 130 construction consolidation.

Target lexical heads:

- `mara` hand
- `jina` foot
- `walu` face
- `milka` ear
- `miyil` eye
- `ngandal` mouth
- `dukul` head
- `muku` back
- `bibar` shin

`kaka` is not treated as a body-part head. It is used only in its sourced sore/pain state sense.

## Source Controls

Dictionary exact-entry pass:

- `mara`: noun, hand.
- `jina`: noun, foot. Track/path sense excluded for this batch.
- `walu`: noun, face.
- `milka`: noun, ear.
- `miyil`: noun, eye. Tree sense excluded for this batch.
- `ngandal`: noun, mouth.
- `dukul`: noun, head. Boat/boss/tape-recorder extensions excluded.
- `muku`: noun, back. Hawk sense excluded.
- `bibar`: noun, shin/ankle. Shin selected; ankle excluded.
- `kaka`: adjective, sore/achey. Taste and salt-water senses excluded.

Grammar controls:

- Patz lists `ngandal` as mouth in the phonetic place table.
- Patz notes `mara` is the free noun root for hand.
- Patz gives productive body-part compounds with `miyil`, `milka`, `walu`, and `mara`.
- Patz gives `dukul-ku` and `nyulu dukul yalbay`.
- Patz gives `bibar-a` shin.
- Patz gives `milka-kari` deaf/no ears.
- Patz gives `miyil-dandi` sleepless.
- Patz gives `mara julurri-ji-y` hand wash-REF.
- Patz gives `jina` foot examples including stepping and `jina-nga`.
- Patz gives `muku kaka` sore back.
- Patz gives `walu-wukurri-ny` turned around.

## Risk Controls

- No generator-authored sentences.
- No new instruments, comitatives, alienable possessives, or temporal clitic constructions.
- No phantom lexemes or unsourced analogies.
- Common-noun A in transitive rows kept ergative.
- Pronoun A kept bare.
- `jina` kept as foot, never track/path.
- `miyil` kept as eye, never tree.
- `bibar` kept as shin, never ankle.
- `kaka` kept as sore/pain, not a concrete body-part noun.
