Prefix Pairs That Reverse a Finding

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

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

Show

Six reversals, each shown on a shared root.

Watch for

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