Correct spelling

bestiality

Correct spelling, explanation: bestiality is a word clearly built on the same base as the word beast so it may seem like this spelling is incorrect. On the contrary, bestiality is the correct spelling, as the word is rooted in the Latin word bestia, and beast is just an anglicized, adjusted spelling.

Definition of bestiality:
noun
1. savage, cruel, or beast-like behavior

Incorrect spelling

beastiality

Incorrect spelling, explanation: beastiality may seem like a correct word, because of its similarity to beast, but it’s not. Why? The base word for both is Latin bestia, and while beast was historically used often, it had the opportunity to be anglicized, and bestiality was not used nearly as often, so it stayed closer to the original Latin word.
