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 Substantial Word™.
Use the examples below to find the rule.
Note: there is a rule for being on the Substantial list and a rule for being on the Insubstantial list. You must find both.
Substantial Words™ | Insubstantial Words™ |
---|---|
dwindled | terminology |
flabbergasted | marshmallows |
tablecloth | mathematician |
abridged | splittable |
welcoming | maintain |
overcast | diminutive |
hamburger | pseudonym |
accomplishment | psychotherapists |
segregation | nowhere |
breadboard | probably |
Many more Substantial and Insubstantial Words exist and are not listed above. Some English words are neither substantial nor insubstantial and some are both.
What is the special rule these words conform to?
