Mathematical Left White Square Bracket ⟦
Usage snapshot:
- Used in content written with the Common script; suitable for UI labels and body text.
- Appears in the Unicode block Miscellaneous Mathematical Symbols-A.
History & usage: The MATHEMATICAL LEFT WHITE SQUARE BRACKET depicts the official name in its name_en. The tokens LEFT and BRACKET mark position and function, while WHITE SQUARE signals its geometric outline. In general typography and notation, LEFT points to a delimiter at the start of a paired symbol, and BRACKET indicates enclosure or grouping. The word MATHEMATICAL places the sign in a formal notation domain, guiding its use in diagrams, formulas, and scholarly work.
Usage contexts arise from its form and category. In math texts, it appears as a delimiter in equations and arrayed expressions. In dictionaries and grammars that annotate mathematical semantics alongside prose, it helps illustrate structure and operator scope. In archival transcription and paleography, it serves as a reference delimiter in older documents and typographic specimens. In educational primers or typographic revivals, it helps learners recognize standard bracket shapes and their spatial rules for quick UI controls in calculators or formula editors. If the block ever signals an EXTENDED variant, treat it as a historical specialist form; otherwise it remains a regular symbol of grouping. Cross platform, accessible names and high contrast help users with screen readers and assistive tech.
