A person or device that dilutes something, or something capable of diluting other substances.
Formed from 'dilute' (verb) plus the agent suffix '-er,' meaning 'one who or that which dilutes.' The root verb 'dilute' comes from Latin 'diluere.'
A 'diluter' could be a person carefully measuring medicines, a nozzle on a cleaning product, or even a politician's promises—the word perfectly captures anything that weakens or stretches something out.
