Comment se fait-il que la négation fonctionne différemment en turc selon qu'on ait affaire à un nom ou à un verbe ?
Negation

The two groups of sentences have different ways of forming negation. A nominal sentence can be negated with the addition of the word değil. For example, the sentence above would become Necla öğretmen değil ('Necla is not a teacher'). However, the verbal sentence requires the addition of a negative suffix -me to the verb (the suffix comes after the stem but before the tense): Necla okula gitmedi ('Necla did not go to school').
Négation

Les deux groupes de phrases ont des manières différentes de former la négation. Une phrase nominale peut être niée par l'ajout du mot "değil". Par exemple, la phrase ci-dessus deviendrait "Necla öğretmen değil" ('Necla n'est pas une enseignante'). Cependant, la phrase verbale nécessite l'ajout d'un suffixe négatif -me au verbe (le suffixe vient après la racine mais avant le temps) : "Necla okula gitmedi" ('Necla n'est pas allée à l'école').

### Draft ###

### 1. Query Decomposition

"Comment se fait-il que la négation fonctionne différemment en turc selon qu'on ait affaire à un nom ou à un verbe ?"

Translation: "How come negation works differently in Turkish depending on whether one has to do with a noun or a verb?"

Key assumption to verify: Is this actually true? Do nouns vs verbs behave differently for negation in Turkish?

### 2. Initial Assessment

Simple information retrieval? No. Requires synthesis across:
- Turkish morphology (nominal vs verbal predicates)
- Negation patterns in agglutinative languages  
- Cross-linguistic negation typology

?Potential issues?: User might have incorrect premise. Many languages show predicate type distinctions for negation.

### 3. Turkish Negation Patterns

⟨H≈0.3⟩ Turkish negation... what do we know? Verbal negation typically uses suffixes. -ma/-me for present, -mam/-mem for past, -mayacak for future. Nominal negation? Separate particle değil. But wait - is this the full story?

● High confidence: Turkish does distinguish between nominal and verbal predicates
◐ Partial: Need to verify the specific patterns claimed

### 4. Syntactic Structure Analysis  

Nominal sentences in Turkish:
- Subject + predicate (noun-like)
- Teacher = Necla (Turkish: Necla öğretmen)
- Negation: Necla öğretmen değil ("Necla is not a teacher")

Verbal sentences:
- Subject + verb + (object)
- Necla went to school (Turkish: Necla okula gitti)  
- Negation: Necla okula gitmedi ("Necla didn't go to school")

→ Pattern confirmed: different mechanisms for nouns vs verbs

### 5. Cross-Linguistic Context

⟨H≈0.8⟩ Negation across languages... English mostly verbal morphology too (can't say "John not teacher"), but Turkish takes it further with the değil particle. Japanese similar patterns. Chinese complex negation constructions. What drives these differences?

!Key insight: Predicate type affects negation because they're syntactically different entities in Turkish.

### 6. Morphological Constraints

Turkish verbal negation:
- Suffixation: git- + -me + -di = gitmedi
- Always suffixes after stem, before tense marker
- Complete morphological integration

Turkish nominal negation:
- Separate particle: değil
- Post-predicate placement
- Minimal morphological integration

∴ Structural differences → different negation strategies

### 7. Verification & Synthesis

Query premise: ✓ confirmed
- Nouns take değil particle
- Verbs take -me suffix  
- Different mechanisms for different predicate types
- Cross-linguistically common pattern

NB: User's French example correct ("enseignante" = teacher, "n'a pas marché" = didn't work)

### 8. Answer Construction

Turkish negation operates via two distinct systems:

**Nominal negation**: Uses the particle "değil" following the noun phrase.
- Structure: [Subject] + [Predicate (noun)] + değil
- Example: Necla öğretmen değil ("Necla is not a teacher")

**Verbal negation**: Applies negative suffixes directly to the verb stem.
- Structure: [Subject] + [Verb stem] + -me + [Tense]  
- Example: Necla okula gitmedi ("Necla didn't go to school")
- Suffix placement: always after stem, before tense markers

This distinction reflects Turkish's agglutinative nature, where verbal morphology integrates negation via suffixes while nominal structures employ separate particles. Cross-linguistically common pattern.

### Answer###
En turc, la négation fonctionne effectivement différemment selon que l'on traite d'une phrase nominale ou d'une phrase verbale.

Pour les phrases nominales, la négation s'effectue par l'ajout du mot "değil" après le nom ou l'adjectif. Par exemple, dans la phrase "Necla est enseignante" (Necla öğretmen), la forme négative devient "Necla n'est pas enseignante" (Necla öğretmen değil).

Pour les phrases verbales, la négation suit un mécanisme différent. Le verbe lui-même est modifié par l'ajout d'un suffixe négatif -me qui se place après la racine verbale mais avant les marques de temps. Ainsi, la phrase "Necla est allée à l'école" (Necla okula gitti) devient "Necla n'est pas allée à l'école" (Necla okula gitmedi) avec l'ajout du suffixe -me au verbe "aller".

Cette distinction reflète la structure grammaticale du turc, où les phrases nominales et verbales font l'objet de traitements syntaxiques et morphologiques différents pour exprimer la négation.
