What does desalinized mean?
"Desalinized" is the past tense and past participle of the verb "desalinize," meaning that salt has been removed from something — most commonly from seawater or brackish groundwater. The word arises almost entirely in technical and practical contexts: engineers describe water as having been desalinized once it passes through a treatment facility, whether by reverse osmosis, distillation, or electrodialysis. Its use signals a processed, purified state, in contrast to raw saline water, which is undrinkable and unsuitable for most agriculture. The term shares its root with "saline" and "salinity," all tracing back to the Latin word "sal," meaning salt. A closely related spelling, "desalinated" (from "desalinate"), means exactly the same thing and is at least as common in modern usage, particularly in American English. Readers encounter "desalinized" most often in journalism about water scarcity, drought relief, and coastal cities that depend on large-scale desalination plants for their drinking supply. The word carries no emotional connotation; its value lies in precision, denoting a concrete technological transformation of the sea into potable water.

Etymology of desalinized
The word derives from the prefix "de-" (indicating removal) combined with "saline," from Latin "salinus" (salty), itself rooted in "sal," the Latin word for salt. English formed both "desalinize" and the variant "desalinate" in the modern era, as large-scale water treatment technology developed during the twentieth century. Cognate words sharing the salt root include "salary" — originally a Roman soldier's salt allowance — and "salad," literally a salted dish.

How desalinized is actually used
The word belongs chiefly to technical and scientific registers — engineering, environmental science, and journalism about water infrastructure. In everyday speech people more often say "desalinated" or refer to "desalination plants" rather than using the verb form directly.
Easily confused with desalinized
"Desalinated" is simply a spelling variant of the same word built on the base "desalinate"; both forms mean having salt removed, with "desalinated" somewhat more common in American usage.
