What does ballpoint mean?
A ballpoint is a common writing instrument — more fully called a ballpoint pen — that dispenses thick, oil-based ink through a tiny rotating metal ball set into the tip. As the ball rolls across paper, it picks up ink from an internal reservoir and deposits it evenly on the page, producing quick-drying lines that rarely smudge. Invented commercially in the 1930s–40s by László Bíró and his brother György, the ballpoint transformed writing by replacing messy fountain pens and fragile quill-era technology with something cheap, reliable, and portable. The word functions almost entirely as a noun, though "ballpoint" can occasionally refer to the pen's tip itself. It carries no strong connotation: it is the neutral default pen of offices, schools, and homes worldwide. Related terms include the British colloquialism "biro," after Bíró himself, and phrases like "ballpoint pen" and "ballpoint ink." Few objects are as universally familiar, which makes "ballpoint" a word everyone uses but few ever pause to define.
A pen with a small rotating metal ball at its tip that transfers oil-based ink from an internal reservoir onto paper.
"He filled out the entire application form in ballpoint."
The writing tip or point of a ballpoint pen.
"The dried ink had clogged the ballpoint, so she swapped in a fresh refill."
This sense usually appears in contexts about refills, maintenance, or how the pen works rather than everyday writing.
Standard regular plural; typically refers to multiple ballpoint pens rather than multiple tips.
"The drawer was cluttered with loose ballpoints and rubber bands."
The ballpoint pen was so revolutionary in 1945 that thousands of New Yorkers queued for hours and paid $12.50 each — roughly $200 today — just to own one.

Etymology of ballpoint
The term "ballpoint" combines the English nouns "ball" and "point," describing the pen's defining mechanism: a small sphere at the tip. The device takes its name from Hungarian journalist László Bíró, who patented the practical design in the late 1930s with his brother György, leading to the British nickname "biro." Commercial production began in Argentina and then spread to Britain and America in the mid-1940s, when the word entered widespread use alongside the object it names.
How ballpoint is actually used
"Ballpoint" is informal-to-neutral register and is often used interchangeably with "ballpoint pen"; in everyday speech people frequently say simply "a biro" (British English) or "a ballpoint" without further specification.
Easily confused with ballpoint
A fountain pen delivers liquid ink through a nib, whereas a ballpoint uses a rolling ball to dispense thicker, oil-based paste ink.
