If a word conforms to a special rule, I call it a Mostly Ruddy Word™.
Use the following examples below to find the rule.
And, if you want to analyze, here is a CSV version:
Mostly Ruddy Words™,Not Mostly Ruddy Words™ NAMETAG,IDENTIFICATION RAILWAY,TRACK WHIMPER,BLUBBER WATERJET,AIRJET MONOLOGUE,SPEECH INDULGE,ENTERTAIN ZOOLOGY,MEDICINE ALLERGEN,IRRITANT SCALLOPS,CRAWFISH CLOUDSCAPE,SCENERY SOLILOQUY,DISCOURSE BOOKKEEPER,LIBRARIAN HALLELUJAH,ALLELUIA STYLOGRAPHY,ELABORATENESS
I have added two footnotes to the image. The words are in the order they're in on purpose although there's no direct correlation between one word and the next. The words at the bottom are more mostly than those at the top with the exception of the last word, which is more ruddy.
You may think I made a typo or left out a word in Addition 1, but I assure you that is not the case. Here's a new idea: none of the words in the table above are ruddy as they currently appear. They are all extremely mostly, though. With a quick transformation, they all become mostly ruddy except for
HALLELUJAH(which is too mostly) and
STYLOGRAPHY(which is too ruddy).
