What is eldritch? How to use in English

The word "eldritch" originated from the Middle English word "eldritch," which means "old and strange." It is a compound word made up of the Old English words "eald" (meaning "old") and "ritc" (meaning "strange" or "ghostly"). In the context of horror and supernatural fiction, "eldritch" carries a more ominous and unsettling connotation. It often describes things that are genuinely frightening, mysterious, and otherworldly in nature, such as eldritch horrors, eldritch Dawn, and eldritch terrors of the Unseen. Stephen King, a prominent writer in horror fiction, popularized the use of the word in the late 20th century. He used it in his novel "The Call of Cthulhu," which is based on a story by H.P. Lovecraft. Lovecraft himself employed the term in his own works, particularly in his Cthulhu Mythos. Overall, "eldritch" is a word that adds richness and depth to the horror genre, capturing the eerie, undefined nature of disturbing occurrences or supernatural entities that lie beyond the boundaries of man's understanding.
