Denitrified

Part of speech: adjective, verb

Definitions

1. Converted nitrates or nitrites into nitrogen gas or other nitrogenous compounds, reducing soil or water nitrogen content; removed nitrogen compounds through microbial processes; undergone a biochemical change where nitrogen is released from compounds as gas
2. Transformed oxidized nitrogen compounds into gaseous nitrogen, typically by bacteria in soil or water; reduced nitrate presence via biological activity; involved in the nitrogen cycle by converting nitrates to nitrogen gas
3. Biologically converted nitrogen compounds like nitrates into nitrogen gas, thereby decreasing nitrogen availability; processed by denitrifying microbes; participating in environmental nitrogen removal through transformation of nitrogen species

Etymology: "Denitrified" is the past tense and past participle of "denitrify," a technical coinage built in modern scientific English from three parts. The prefix "de-" means "removing or reversing," from Latin "dē," which here strips something away. The middle element comes from "nitro-," a combining form of "nitre" (saltpetre), itself from Ancient Greek "nítron," a word for a natural alkaline salt. The ending "-ify," inherited through Old French "-ifier" from Latin "-ificare," means "to make or convert into." Put together, the verb means to make something lose its nitrogen compounds. The sense of the word is therefore nearly literal: a denitrified soil or sediment is one from which microbes have converted nitrates into nitrogen gas, which escapes into the air. Nothing in the word's building blocks mentions microbes, so the biological meaning had to be spelled out by the scientists who used it.
