The root word that means "dread of" is "phobos" or "phobia." For example, "arachnophobia" means the fear or dread of spiders.
Adding the suffix "-phobia" to a root word creates a noun indicating an irrational fear or aversion towards the root word.
The root meaning of claustrophobia comes from the Latin word "claustrum" meaning enclosure or confined space, and the Greek word "phobos" meaning fear. Combined, it refers to the fear of enclosed spaces.
Arachno = spider phobia = fear
