leftwards harpoon with barb downwards

Leftwards harpoon with downward barb

38/104

↽ is a left-pointing harpoon used as a mathematical relation mark. In a formula, its exact meaning comes from the notation the author defines; LaTeX typesets it with \leftharpoondown in math mode. Its downward barb distinguishes it from the upward-barb partner .

Text symbol

What ↽ means

It marks a leftward harpoon relation in mathematical notation. LaTeX treats it as a relation symbol; the mark alone does not define one universal relationship, so read it according to the notation for that formula.

As a text character, ↽ is drawn by the active font, so its proportions can vary. Its leftward shaft and downward barb identify the form.

Technical mathematical notation; its role depends on the notation used in the formula.

Keep the barb: is a plain left arrow, not this harpoon.

Why does ↽ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
