Scope Means a Target to Aim At
Scope is the extent of something. The Greek word behind it meant a mark to aim at, and it survives in dozens of instrument names.
Scope is the extent or range of something, and informally any viewing instrument. Greek *skopos* meant a mark to aim at and *skopein* meant to look — so scope began as a target and became a field of view. The suffix *-scope* now names dozens of instruments, all of them for looking: microscope, telescope, stethoscope, periscope, kaleidoscope. A *stethoscope* is literally a chest-looker, even though it works by ear.
- Extent or range. *Beyond the scope.*
- Room to act. *Scope for improvement.*
- A viewing instrument. *A rifle scope.*
- -scope — an instrument suffix. *Telescope.*
- Greek — *skopein*, to look. *The source.*

Why do so many instruments end in -scope?
Because the Greek root means to look, so the suffix was the natural way to name any viewing device.
Why is a stethoscope called a looker?
The suffix had broadened to mean examining rather than strictly seeing. A stethoscope examines the chest, by ear.
