A floppy disk.
"Please insert the floppy disk into the drive to save your file."
Limp, not hard, firm, or rigid; flexible.
"The old man's ears were long and floppy as they swung behind his head when he walked."
In plain English: Floppy means something that is soft and bends easily instead of staying stiff.
"The old dog has such floppy ears that they flop over his eyes when he runs."
Usage: Use "floppy" to describe objects that are limp and lack structural support, such as deflated balloons or sagging curtains. Avoid using it interchangeably with "flexible," which implies the ability to bend without breaking rather than a state of being soft and shapeless.
The word floppy is a compound formed from flop and the suffix -y to describe something that bends easily or lacks stiffness. It entered English as a straightforward combination of these existing elements rather than through borrowing or complex evolution.
