Use "ailurophobia" in a sentence
"The correct word for describing hatred of cats is "ailurophobia"."
"Most of said adjectives are formed off the latin roots -- equine, feline, bovine, etc. (although - phobias are, naturally, formed off the Greek; hence ailurophobia for fear of cats, instead of something like felinophobia, which would mix a Greek suffix on a Latin root -- eek, cringe)."
"Your friend Chip's ailurophobia acts up every Halloween."
