What does arider mean?
"Arider" is the comparative form of the adjective "arid," which describes land, climates, or conditions that are extremely dry and lacking in moisture. To say one region is arider than another is to state that it is even more parched, barren, or water-starved than its counterpart. The word derives from the Latin "aridus" (dry), via the English adjective "arid," which entered the language in the seventeenth century. In practice, "arider" is relatively uncommon in everyday conversation, since speakers tend to use the simpler comparative "drier" or the periphrastic "more arid." It finds its natural home in scientific and descriptive writing — climatology, geography, ecology — where precise gradations of dryness matter. Its connotations are stark and somewhat bleak, evoking desert landscapes, drought, and scarcity. Related forms include the superlative "aridest" and the nouns "aridity" and "aridness," which name the quality of extreme dryness itself.

Etymology of arider
"Arider" is formed by adding the regular English comparative suffix "-er" to "arid," an adjective borrowed from the Latin "aridus," meaning dry or parched, which itself traces back to the Latin verb "arere," to be dry or burnt up. English adopted "arid" in the early seventeenth century, and comparative and superlative forms such as "arider" and "aridest" followed as natural grammatical derivations. The same Latin root also underlies "aridity" and related dryness vocabulary.
