The QWERTY layout is often explained as a way to keep early typewriter keys from jamming together.

The longer version

Mechanical arms carrying the letters swung up to strike the paper, and two arms rising from neighbouring positions could lock together. The standard arrangement is said to have been chosen to separate frequently paired letters so that a fast typist would not collide them, and to spread work between the hands.

Historians argue about how much of that is the real reason; the layout also suited early sales demonstrations and may have been shaped by telegraph practice. What nobody disputes is the outcome: once thousands of typists learned it, changing became impractical. Later rival arrangements claimed better speed and comfort and still failed to displace it.
