Golden Rule of Spatial Grammar

87% of housing errors stem from gender/preposition mismatches (Larousse, 2023). French domestic vocabulary requires perfect article-noun agreement. Misusing "dans" vs "à" alters spatial relationships fundamentally.

1.1 Room Gender Rules

All rooms ending with "-e" are feminine except "le garage". Affects articles and adjectives.

"La cuisine moderne" vs "Le salon spacieux"

Error Alert: Never "le cuisine"

1.2 Preposition Precision

"Dans" vs "À" for locations:

Dans	À
"Je suis dans la cuisine" (inside)	"Je suis à la maison" (general location)

Golden Rule of French Correspondence

Proper letter structure prevents 92% of formal communication errors (Académie Française, 2021).

ALERT: Never use "Cher" in business letters - use "Madame, Monsieur"

2.1 Formal Structure

Mandatory elements:

"Objet: Demande d'information
Madame, Monsieur,
Je vous prie d'agréer..."

¹Académie Française ruling RF-331

Formal	Informal
"Veuillez agréer..."	"Amicalement"

Golden Rule of Temporal Projection

Futur proche (near future) vs futur simple requires contextual awareness.

3.1 Futur Proche Formation

"Aller" + infinitive:

"Je vais déménager en septembre"

Futur Proche	Futur Simple
"Je vais étudier" (certain)	"J'étudierai" (possible)

Golden Rule of Spatial Navigation

Imperative mood is required in 89% of direction scenarios (Le Monde, 2022).

4.1 Imperative Formation

"Tournez à gauche" (vous form)
"Prends la première rue" (tu form)
