Curious. Spacious. Hilarious. All these words and hundreds more end in the -ious suffix, which gives the meaning "full of" or "having the qualities of" to its base words. Based on Latin, the -ious ending typically changes a noun into an adjective. For example, in a fundamental sense, "spacious" means "full of space." Adding the -ious suffix requires removing one or more letters from the original word: "space" loses an E to form "spacious." This rule also works in reverse with most comments. Removing -ious from the word "mysterious," you are left with something full of mystery. Solve this word search puzzle to learn such words. All the best!
