Subset Symbol ⊂

For equations and symbolic work, Subset Symbol uses ⊂, recorded as U+2282 (SUBSET OF). ⊂ is U+2282 SUBSET OF. It states that every element of the left-hand set belongs to the right-hand set, although authors differ on whether equality is allowed. Useful checks are A ⊂ B, {1,2} ⊂ {1,2,3}, S ⊂ ℝ, and If A ⊂ B, examine membership. These examples keep operands, grouping, and the symbol’s mathematical role visible. Keep the page’s intent exact. A visual resemblance alone is not enough to substitute another glyph. Frequent failures include assuming every textbook defines ⊂ identically, confusing ⊂ with element-of ∈, and using ⊂ where ⊆ is intended. For Subset Symbol, confirm that the pasted text still contains ⊂ and has not been replaced by a visually similar form. Formatting should follow these retained rules: state whether ⊂ allows equality in the document, use ⊆ when subset-or-equal must be explicit, keep set names on both sides of the relation, and use equation markup for complex set expressions. The page records HTML decimal ⊂, HTML hexadecimal ⊂, and CSS escape 2282. Test the rendered result because font and emoji presentation can differ. A useful scope question is “Does ⊂ mean a proper subset?” The reviewed answer is: Often, but not universally. Define the convention or use ⊊/⊆ to remove ambiguity. Typing can be checked in two environments. Windows: In Microsoft Word, type 2282 and press Alt+X. For the subset symbol entry, in other Windows apps, use Character Map or copy ⊂ from this page. macOS: Open Character Viewer with Control+Command+Space and search for “subset of,” or copy ⊂. A reliable final check is to compare the saved text with U+2282, review the surrounding label, and test the target font or application before the page is published.
