Meaning
The infinity symbol ∞ is a lemniscate: a sideways figure eight with no start and no end. John Wallis introduced it in mathematics in 1655 to mean a quantity without bound. That simple loop then moved into jewelry, tattoos, and logos as a compact sign of forever — love that does not run out, a bond that loops back, a process that continues.
Copy-paste the infinity symbol whenever you need the real Unicode character (U+221E), not a lookalike. It pastes into Instagram bios, Word docs, and chats as plain text. On Windows, Alt+236 often types it; on Mac, Option+5 in some layouts.
As a tattoo, ∞ often means eternal love, unbreakable friendship, or recovery that keeps going. An infinity symbol with a heart — or an infinity-heart tattoo — ties “forever” to romance. Infinity jewelry (necklaces, rings, bracelets) carries the same message as a gift for partners, parents, and close friends.
The rainbow or gold infinity loop is also widely used in autism and neurodiversity pride, standing for infinite variation in human minds — a different reading from the puzzle-piece motif. When you wear or ink ∞, it helps to know which of these meanings you intend.
Symbolstacks uses the true infinity glyph for copy-paste. Illustrated ouroboros (a snake eating its tail) is a related “endless cycle” image, but it is not the same character.
Origin
Mathematical lemniscate popularized by John Wallis in 1655; later adopted in jewelry, tattoo culture, and disability-pride design.
Cultural variations
In math and science it means unbounded quantity. In romance it means forever. In memorial jewelry it can mean a bond that outlasts death. In autism and neurodiversity communities a rainbow infinity often means infinite neurological variation. Alchemical and occult art sometimes prefers the ouroboros for cyclical eternity instead of the lemniscate.
Frequently asked questions
How do I copy and paste the infinity symbol?+
Click ∞ on this page to copy it, then paste with Ctrl+V or Cmd+V. On many Windows keyboards Alt+236 also types it. It is Unicode U+221E, so it works as real text in bios, docs, and chats.
What does the infinity symbol mean?+
It means something without end: unbounded quantity in math, and forever, loyalty, or unbroken connection in jewelry and tattoos.
What does an infinity symbol tattoo mean?+
An infinity tattoo usually means eternal love, friendship, or personal continuity. People often place it on the wrist, behind the ear, or along a finger.
What does infinity jewelry mean?+
Infinity necklaces, rings, and bracelets are given as “forever” gifts — for partners, family, or friends — using the same endless-loop meaning as the tattoo.
What does an infinity symbol with a heart mean?+
Combining ∞ with a heart (or an infinity-heart tattoo) emphasizes endless love or an unbreakable romantic bond, rather than a purely mathematical reading.
What does the infinity symbol mean for autism?+
A gold or rainbow infinity loop is widely used as a neurodiversity and autism-pride mark, standing for infinite variation in how people think. It is distinct from the older puzzle-piece logo, which many autistic advocates reject.
