# What is a CPO Word?™

This is in the spirit of the What is a Word™/Phrase™ series started by JLee with a special brand of Phrase™ and Word™ puzzles.

If a word conforms to a special rule, I call it a CPO Word™.
Use the examples below to find the rule.

CPO Words™ Not CPO Words™
ANIMAL BEAST
BULKY HUGE
FEATHER POULTRY
IGNITE BLAZE
JEANS SLACKS
MAY JUNE
NERVOUS ANXIOUS
PUBLIC DISCRETE
REPLACE DISPLACE
SPELUNKING EXPLORING
UNSTABLE TEETERING
VOICE CRY

In case you want it in CSV:

CPO Words™,Not CPO Words™
ANIMAL,BEAST
BULKY,HUGE
FEATHER,POULTRY
IGNITE,BLAZE
JEANS,SLACKS
MAY,JUNE
NERVOUS,ANXIOUS
PUBLIC,DISCRETE
REPLACE,DISPLACE
SPELUNKING,EXPLORING
UNSTABLE,TEETERING
VOICE,CRY


The puzzle relies on the series' inbuilt assumption, that each word can be tested for whether it is a CPO Word™ without relying on the other words.

These are not the only examples of CPO Words™, many more exist and can be found.

Let someone else do the searching.

• The hint makes me think of SEO, but I am unable to sort the words based on that criteria. Nov 30, 2016 at 4:57
• Is the acronym (CPO) helpful in solving this puzzle? Or will we only see what it meant afterwards? The hint is not really helping me either so far... Dec 5, 2016 at 10:59
• I'd say so. It's a common use of the acronym, at least in the USA

I think a CPO Word™ is one which has been

used before in the What is a Word™/Phrase™ series either as a positive or negative example.

Examples are -

ANIMAL : What is an Anagrammable Word™?
BULKY : What is an Odious Word™?
DEGRADE : What is a Spaced Out Word™?
FEATHER : What is a Perfect Word™?
IGNITE : What is a Tellygraph Word™?
JEANS : What is a Veteran Word™?
MAY : What is an Inflated Word™?
NERVOUS : What is an Uptight™ Word?
PUBLIC : What is an Explosive Word™?
REPLACE : What is a Conflicted Word™?
SPELUNKING : What is an Energetic Transmitter Word™?
UNSTABLE : What is a Rotary Club Word™?
VOICE : What is a Chaotic Word™?

They are called CPO words as this is an abbreviation for

Cerified Pre-owned - credit for this is due to Levieux - who let someone else do the searching.
