Looking for the longest "non-variant" word [closed]
I'm looking for the longest English word that has no variants, where a variant might be
- A singular or plural form
- A conjugated form
- A form in another part of speech
For example, mouse would fail by all those rules: it has a plural ("mice"); as a verb, it has conjugated forms ("mousing", "moused"); it has an adverbial form ("mousy") and other noun forms ("mouser").
Obviously, pretty much any verb would be out, as would any countable noun that has a plural. I'm also excluding words that are just conglomerations of other words like "whatsoever".
Right now, I've got some five-letter word -- "moose", "there" -- and "through", which has seven but I'm thinking should be excluded because of "throughway" and "throughput".
Schadenfreude — Though this word has variants in German, it lacks them in English.
Usually the invariable words are the function words: interjections, adverbs, etc.
I excluded:
- Words like "underground", which I thought you could disagree with as under + ground;
- Words like "intentionally", because it had variants like "intentional" or "unintentional";
- Words like "old-fashioned" because of both the reasons above.
So, selecting among them, I could find:
- Draconian = 9 letters;
- Tomorrow = 8 letters.
OBDIPLOSTEMONOUS = 16 letters
RHADAMANTHINE = 13 letters
ZENZIZENZIZENZIC = 16 letters
Definition of obdiplostemonous: Having twice the number of stamens as the number of petals. Definition of rhadamanthine : Rigorously just and severe.
Definition of zenzizenzizenzic: The eight power of a number
If medical terms count, how about the 45-letter standard English word
pneumonoultramicroscopicsilicovolcanoconiosis
which of course means "black lung disease"?
I know of no variants. I don't see a rule against combination words, just forms of the same word. Does anyone else know of a variant to this one?
(Too bad variants are excluded. My favorite longest one-syllable word is "strengths." Nine letters. Yes, it has variants, but one syllable, you know...?)
