Precedes Above Single-line Not Equal To Symbol
⪱ is a mathematical comparison symbol indicating “precedes” above a “not equal to” condition.
U+2AB1
⪱ is a specialized Unicode math symbol used in formal notation. It combines a “precedes” idea with a “not equal to” meaning in a single glyph. Use it in equations, proofs, and typeset documents when that exact operator is needed.
Precedes Above Single-line Not Equal To Symbol Meaning
⪱ (Unicode U+2AB1) is named “PRECEDES ABOVE SINGLE-LINE NOT EQUAL TO.” In math contexts, it signals a relationship where one side is “preceding” while the corresponding value is explicitly “not equal.” Because it’s a less common, high-specificity symbol, it’s typically used when a standard not-equal symbol alone isn’t enough to convey both ordering and inequality style. If you’re matching a particular notation system or existing document, copy the exact character to avoid mismatched semantics or typography. For most plain-text workflows, prefer direct copy/paste or use the provided HTML/CSS/JS escapes.
Common uses
- •Writing formal math expressions that combine ordering (“precedes”) with inequality (“not equal”).
- •Editing or proofreading technical documents where the exact glyph must match an existing notation.
- •Typesetting in environments that support Unicode math characters (e.g., rich text editors and some renderers).
- •Labeling logical or sequence-based conditions in diagrams and educational materials.
- •Using the symbol in LaTeX/MathJax-compatible workflows where direct Unicode input is accepted.
Examples
⪱ Precedes Above Single-Line Not Equal To
- ⪱If a ⪱ b, then a is considered to precede b but is not equal.
- ⪱The relation x ⪱ y rules out equality while preserving the “before” direction.
- ⪱In this proof, we assume n ⪱ m to express a strict non-equality constraint.
- ⪱Let p ⪱ q; the constraint captures precedence combined with “not equal.”
- ⪱When comparing terms, use ⪱ instead of plain ≠ to reflect the intended order.

FAQ
What does ⪱ mean in math notation?
⪱ means “precedes above single-line not equal to,” combining a precedence relationship with a not-equal condition (Unicode U+2AB1).
How can I copy ⪱ into HTML or a website?
You can paste the character directly, or use the provided HTML entity: ⪱.
How do I include ⪱ in CSS or JavaScript?
Use the CSS escape \\2AB1 or the JavaScript escape \\u{2AB1}.
Is ⪱ the same as the normal “not equal to” symbol?
No. While ⪱ includes a “not equal to” component, it also encodes a “precedes” relationship, so it’s not a direct replacement for ≠.
