Prefix Pairs That Reverse a Finding

Captions available

The idea

Six prefix pairs reverse the meaning of a term while changing one or two letters, and each pair attaches to the same roots.

In practice

Six reversals, each shown on a shared root.

Where people slip

Five of these pairs are true opposites. The sixth is a sound-alike, and treating it as an opposite is its own error.
