This puzzle is based off the What is a Word™ series started by JLee
If a word satisfies a certain property it is called a Dime Word™. Here are some examples:
|Dime Words™||Not Dime Words™|
Dime Words™,Not Dime Words™ KARMA,ECHO PHOENIX,THUNDERBIRD PANTHEON,VALKYRIE CYPHER,ZERO VIPER,LESION RAZE,REAPER BREACH,BASTION SAGE,MAESTRO TALON,SIGMA KINDRED,MERCY RUMBLE,PULSE NAUTILUS,LION
What is the rule to tell whether a word is a Dime Word™ or not? Why is it called a Dime Word™?
(Note that each word can be tested for whether it is a Dime Word™ on its own, without looking at any of the other words in the list of examples. And hello from the Maths Stack.)
