What does dilutable mean?
"Dilutable" is an adjective describing something—usually a liquid—that can be diluted, meaning thinned or reduced in strength by adding another substance such as water or a solvent. It appears most often on product labels and in technical writing: a dilutable concentrate, for instance, is sold in strong form so the buyer can mix it to the desired strength at home. This makes the word common in contexts ranging from household cleaning products and fruit cordials to pharmaceuticals and industrial chemicals, where adjustable concentration offers flexibility, economy, and easier storage or transport. The word derives from "dilute," which traces back through Latin diluere, "to wash away" or "dissolve." While "dilutable" is neutral in tone, its frequent pairing with words like "concentrate" reflects a practical appeal: buying something dilutable often means paying less for packaging and shipping than for the active ingredient itself. It should not be confused with "diluted," which describes something already thinned rather than something capable of being thinned.
adjectiveAble to be diluted; capable of being thinned or weakened in concentration by the addition of another substance, typically water or a solvent.
- Capable of being thinned or reduced in strength or concentration by mixing with another liquid, especially water or a solvent.
"The concentrate is dilutable with up to ten parts water, making one bottle last for months."
"The cleaning fluid is supplied as a dilutable concentrate that must be mixed with water before use."
"Pharmacists often prefer dilutable formulations because they allow flexible dosing for children and adults alike."
That bottle of squash in your fridge is a masterclass in economics: buying it dilutable means you're mostly paying for flavor, not shipping water.

Etymology of dilutable
"Dilutable" derives from the verb "dilute," which entered English from Latin diluere, formed from dis- ("apart") plus lavere/luere ("to wash"). The Latin root literally meant "to wash away" or "to dissolve by washing." The adjective form developed later as technical and commercial language required a term for substances designed to be mixed down from concentrated form. Cognates sharing this watery Latin root include "deluge," from the same idea of overwhelming washing or flooding.
