What does azotize mean?
Azotize is a verb used in chemistry to describe the process of combining or impregnating a substance with nitrogen, the element once known to chemists as azote. In its historical sense, the word appeared in older chemical literature when writers described organic matter undergoing decomposition or transformation into nitrogen-bearing compounds. The term derives ultimately from Lavoisier's naming of nitrogen as 'azote' — literally 'without life' in Greek-derived French coinage — because the gas neither burns nor supports life. Today, azotize is considered obsolete or highly specialized: modern chemistry instead speaks of nitrogen fixation, nitrogenation, or ammonification, terms that carry precise biochemical meanings. Nevertheless, the word survives in dictionaries as a window into how eighteenth- and nineteenth-century scientists talked about one of nature's most important elements, and it remains useful for readers of older scientific texts who encounter it in context.
verbTo combine or impregnate a substance with nitrogen; in older chemistry, to convert a substance into, or treat it as, an azote (nitrogen) compound.
- To combine or impregnate a substance with nitrogen.
- (Historical chemistry) To convert a substance into an azote compound or to regard it as containing azote.
"Early chemists described the process by which organic matter was azotized during putrefaction."
"The soil was azotized over centuries by the slow action of nitrogen-fixing organisms."
"In nineteenth-century chemical treatises, authors described animal matter as becoming azotized during decomposition."
Its name traces back to 'azote' — Lavoisier's word for nitrogen, literally meaning 'without life', because suffocating gas that kills yet sits inert in most of the air we breathe.

Etymology of azotize
Azotize comes from 'azote', the name Antoine Lavoisier gave to nitrogen in the late eighteenth century, formed from Greek roots meaning 'without life' because the gas does not support respiration or combustion. The suffix '-ize' marks it as a process verb in the tradition of chemical verbs like oxidize and hydrogenize. Related words sharing this heritage include 'azote' itself and the adjective 'azoic', both drawing on the same Greek root for lifelessness.

How azotize is actually used
A technical term of historical and specialist chemistry, now rare in modern scientific writing. It appears mainly in older chemical literature and dictionaries rather than contemporary usage.
Easily confused with azotize
Nitrify refers specifically to the conversion of ammonia into nitrates by bacteria, whereas azotize is the broader, largely historical term for combining any substance with nitrogen.
