Root Explanation

Invaluable → It is formed from the prefix "in-" (meaning not) and the root "valuable" (from Latin "valere", meaning to be strong or worth). The word "invaluable" means not able to be valued or priceless, indicating something of such great worth that it cannot be measured.

Memory Tip

Think of something that is 'not' ('in-') just 'valuable' — it means it is so precious that it cannot be assigned a value.
