What does alkalify mean?
Alkalify is a verb meaning to turn something into an alkali or to give it alkaline properties—that is, to raise its pH above neutral. In practical terms, to alkalify a substance such as soil, water, or a chemical solution is to reduce its acidity, often by adding an alkaline material like lime, ash, or a carbonate. The word appears most often in chemistry, agriculture, water treatment, and industrial processing, where precise control of acidity matters. It can also be used intransitively to describe a substance becoming alkaline on its own. Although perfectly correct, alkalify is relatively rare today: modern scientific and medical writing overwhelmingly favors its synonym 'alkalize.' Both words trace back through New Latin to the Arabic al-qily, referring to the ashes of saltwort plants used since antiquity in glassmaking and soap-making. For readers encountering technical texts from earlier centuries, recognizing alkalify as simply an older form of 'to make alkaline' is the key to understanding it.
verbTo convert a substance into an alkali, or to make it alkaline; to treat something so that it acquires the properties of an alkali.
- To convert a substance into an alkali or make it alkaline.
- To become alkaline (used reflexively or intransitively).
"Adding limestone to the soil will gradually alkalify it, raising the pH for crops that dislike acidity."
"The treatment works by using lime to alkalify the acidic wastewater before it is discharged."
"Some gardeners alkalify overly sour soil with wood ash each autumn."
Before chemists settled on 'alkalize,' they reached for this rarer twin—both built on 'alkali,' a word Arabic alchemists gave the world from the ashes they burned to make soap.

Etymology of alkalify
Alkalify was formed in English by combining the noun 'alkali' with the suffix '-fy,' on the model of verbs like 'acidify' and 'liquefy'; it is attested from around the early nineteenth century. The root 'alkali' entered European languages via medieval Latin from the Arabic al-qily, meaning the ashes of the saltwort plant, which were valued for their alkaline salts. Its sibling 'alkalize' arose by the same route and eventually displaced it in everyday scientific use.

How alkalify is actually used
A somewhat formal, technical term found chiefly in older chemistry texts and technical literature; in contemporary scientific and health writing, 'alkalize' is the strongly preferred equivalent.
Easily confused with alkalify
Alkalize and alkalify mean virtually the same thing—to make alkaline—but alkalize is far more common in modern scientific and medical writing.
Alkaline is an adjective describing something that has the properties of an alkali, whereas alkalify is the verb describing the act of making it so.
