If a word conforms to a special rule, I call it an Antigrammatic Word™.
Use the following examples below to find the rule.
However, by spending too much time in The Sphinx Lair, I have got the ""can't post a puzzle unless it has a single word or phrase answer" syndrome". So, once you figure out the rule, you will need to use the Words provided to get an answer that will both annoy you and soothe you at the same time.
|Antigrammatic Words™||Not Antigrammatic Words™|
And, if you want to analyze, here is a CSV version:
Antigrammatic Words™,Not Antigrammatic Words™ KAFIR,ONION SILENT,RELAX UNITED,ADORNED SAINTED,SUNRISE PIT,SPAR HAPPIEST,BEGONE HURTLESS,ANGEL
The puzzle satisfies the series' inbuilt assumption, that each word can be tested for whether it is an Antigrammatic Word™ without relying on the other words.
These are not the only examples of Antigrammatic Words™, more, but a very limited number exist.
What is the special rule these words conform to?
