Definition

Noun: A writing instrument that uses a small, rotating metal ball at its tip to transfer ink from an internal reservoir onto a writing surface.

Usage

A "ballpen" (more commonly spelled as one word: ballpoint pen) is a common, everyday tool for writing. It is designed for reliability and ease of use, as the rolling ball mechanism prevents ink from drying out quickly and allows for smooth writing on most papers.

Examples

• Please sign the form with a ballpen; pencil is not acceptable.
• I always keep a blue ballpen in my bag for taking notes.
• The invention of the ballpen revolutionized everyday writing.

  • The exam instructions stated that answers must be written in black ballpen ink.
