Word dispute : Is "seriosity" a word?

My friend insists that “seriosity” (instead of “seriousness”) is a word in the English language. Can anyone confirm that it is or is not a word? Thank you. :slight_smile:


It’s not a word I know.


But then look at this:

urbandictionary.com/define.p … =seriosity

According to Merriam-Webster Dictionary it is a word.

Thank you for the link, but actually that is the same link that I was sent. Since it doesn’t actually give you it’s definition but rather sends you to a subscription page (as opposed to other normal entries ), this leads me to believe that it is recognized as a spelling mistake. Also, the word doesn’t appear in the Thesaurus section, and furthermore when you type in “seriousness” in the Thesaurus, “seriosity” does not appear in any list of synonyms or related words. This leads me to believe that it is not a word.

I was referring to the Webster’s dictionary link. I only trust either Webster’s or Oxford, none of these internet pseudo-dictionaries.

Hello Alan,

I looked up:1. French,2.Spanish,3.Italian, 4.English -English

1.WordReference.com Dictionnaire Français-Anglais

3.WordReference.com Dizionario Italiano-Inglese
Traduzione di ‘seriosity’ non trovata
4.WordReference.com English Dictionary
No dictionary entry found for ‘seriosity’

I believed that it is a French Word because it similar to ‘serieux’ ‘serieuse’ (adj)= serious / but ‘serieux’ can be a noun.
