What does dye mean?
A dye is a substance — whether extracted from plants, insects, minerals, or synthesized in a laboratory — that imparts lasting color to a material such as cloth, yarn, leather, hair, or paper. Unlike pigments, which sit on a surface as insoluble particles, dyes penetrate and chemically bond with the fibers they color, making them resistant to washing and light. Used as a verb, 'to dye' means to treat a material with such a substance: a craftsperson might dye wool with madder for red or indigo for blue. Dyes have carried enormous economic and cultural weight throughout history; rare colors like Tyrian purple were once symbols of royalty and wealth, while modern synthetic dyes, born from nineteenth-century chemistry, made vibrant color affordable everywhere. Today the word appears most often in contexts of textiles, fashion, and hair coloring.
A natural or synthetic substance used to color materials, especially textiles, by penetrating and bonding with their fibers.
"The artisan prepared a vat of indigo dye."
Often modified by source or type: 'vegetable dye', 'synthetic dye', 'acid dye'.
To apply a dye to a material in order to change or deepen its color.
"They dyed the silk scarves by hand using traditional methods."
Regular plural; used when referring to multiple kinds of coloring substances rather than quantities.
"The shop stocks dozens of natural dyes derived from roots, bark, and insects."
For thousands of years, royal purple dye was so rare and expensive that it was literally worth more than its weight in gold — reserved for emperors alone.

Etymology of dye
'Dye' comes from Old English 'deah' or 'deag', related to Old High German 'tougen', both from Proto-Germanic roots connected to color and concealment. The word has been part of English since before written records in the language begin, reflecting the ancient importance of textile coloring. Its Germanic cognates include words for color and hue in related languages, though no Latin or Greek root is involved — unlike many English color terms, 'dye' is native to the Germanic branch.

Usage notes
Both noun and verb are common and neutral in register. The present participle is spelled 'dyeing' (not 'dying'), which preserves the 'e' to avoid confusion with 'die/dying'. The verb takes direct objects ('dye the cloth') rather than appearing with prepositions like 'paint'.
Don't confuse with
'Die' means to stop living (or a gaming cube), while 'dye' refers to coloring a substance — they sound identical but differ entirely in meaning and spelling.
