除

Core logic: removal or displacement—taking something away from a whole, clearing space, or carving out an exception.

1. Active Removal: The deliberate elimination of physical objects (demolishing barriers, sweeping) or abstract entities (purging influences, canceling debts).

2. Division and Partitioning: Mathematical division (the divisor) and technical partitioning, such as the allotment of shares or land surveying.

3. Temporal Thresholds: The expiration of one period to make room for another; specifically the casting off of the old year (e.g., 除夕).

Functions both as a verb (active removal/division) and as a prepositional marker indicating exception ("except," "aside from").

Compared to 去 (qù) or 汰 (tài), 除 often implies a more definitive or systemic removal, such as stripping away a specific part of a whole.

Tang-period reading: *djhiu djhiu. While later traditions may distinguish tones—such as chú for removal and chǔ for partitioning—these distinctions generally collapse in practice.

When the glyph functions as a marker of exception, determine whether the context describes an active process of exclusion (verb) or is simply defining the boundaries of a group (preposition). In cases of phonetic ambiguity, rely on semantic context—general elimination versus precise measurement—rather than tonal variants.
