Incorrect spelling, explanation: you can’t spell the word horniness as hornyness. If you’re wondering why -y changes into -i (since horny is the word-formation base), here’s the answer: when a word ends in a consonant followed by an -y and you want to change it into a noun by adding the suffix -ness, you typically change the -y to an -i before adding -ness. This spelling change is necessary to maintain the pronunciation of the word. If we were to keep the -y and add -ness directly, it would result in an awkward pronunciation, making it more challenging to read and pronounce the word correctly.

Correct spelling, explanation: the word horniness is derived from the adjective horny, which originally referred to having horns or horn-like projections. Over time, the meaning of horny evolved to describe a state of being sexually aroused or excited. The etymology of horny can be traced back to the Old English word horn, which meant horn or projecting point. The term later developed metaphorically to describe something resembling a horn, such as the horn-like projections on animals. Horniness is the accepted form with the correct etymological roots, while hornyness is a misspelling that deviates from the standard English word formation rules.
