IPA: /dɪˈskɛt/
KK: /dɪsˈkɛt/
A small, flat, portable storage device used to save and transfer data, typically made of plastic and containing a magnetic disk.
I saved my project on a diskette before the computer crashed.
Diskette → The word is derived from "disk" (from Latin "discus", meaning a round plate or disk) and the diminutive suffix "-ette" (from French, meaning small or little). Thus, a diskette refers to a small disk.
Think of a 'disk' being made smaller with the '-ette' suffix, which helps you remember that a diskette is a small disk.
