戶

• Concrete/Architectural: A door, specifically a domestic or single-leaf door.
• Social/Familial: The household or family unit (by metonymy).
• Administrative/Fiscal: A registered household as a census or taxable entity.

• Noun: Subject or object.
• Classifier: Used after numerals to count households, particularly in administrative prose.

• 戶 vs. 門 (mén): Single-leaf/domestic door versus a double-door, grand gate, or primary entrance.
• 戶 vs. 家 (jiā): While both refer to the family, 戶 emphasizes the structural, administrative, or registered unit, while 家 emphasizes kinship and the residential center.
• 宅 (zhái): Refers specifically to the physical dwelling or estate.

Simplified and Z-variants (U+6237, U+6238) are orthographic shortcuts for clerical efficiency and do not indicate a shift in meaning.

In texts regarding governance, population, or taxation, prioritize "registered household" over "door." In philosophical or metaphysical contexts, the glyph may function as a metaphor for a portal or transition point.
