IPA: /dɪˈkʌləraɪzər/
KK: /dɪˈkʌlərˌaɪzər/
A substance or agent that removes color from something, often used in processes like bleaching or dye removal.
The hairdresser used a decolorizer to lighten her client's hair before applying the new color.
Decolorizer → It is formed from "de-" (meaning down or away) and "color" (from Latin "color", meaning hue or pigment) and "-izer" (a suffix indicating an agent or something that performs an action). The word "decolorizer" refers to a substance that removes color or pigment from something.
Think of 'removing color' ('de-' means away and 'color' refers to hue) — that's what a decolorizer does.
