"Philomisia" is not a commonly recognized word in the English language or any other language. It does not appear in standard dictionaries or academic sources.
In Greek, the prefix "philo-" typically denotes love or fondness, while the suffix "-misia" indicates hatred or aversion. However, the specific word "Philomisia" itself is not widely known or accepted.
For someone who dislikes or hates love, the term "philophobe" might be more appropriate. "Phobe" comes from the Greek word "phobos," meaning fear or aversion. So, "philophobe" refers to someone who has an aversion to love or romantic relationships.
Keep in mind that language evolves over time, and new words may emerge or become more widely accepted. If "Philomisia" has gained traction or recognition as a word for someone who hates love in more recent times, I may not be aware of it. However, based on the information available , "philophobe" is a more commonly used term for this concept.
