Having a yellow color or tending toward yellowness, especially the golden-yellow hues found in autumn leaves, flower petals, or mineral specimens. It's the scientific word for that particular warm, sunny yellow that makes you think of honey and sunbeams.
From Greek 'xanthos,' meaning yellow, the same root that gives us 'xanthophyll' (the yellow pigment in plants) and the name Xanthus (meaning golden-haired). This scientific term entered English in the 19th century as botanists and chemists needed precise vocabulary to describe the yellow compounds and colorations they were studying.
I have such a soft spot for this word because it starts with that mysterious X that sounds like Z — ZAN-thick — and it's all about the most cheerful color in the world! The ancient Greeks were so fascinated by yellow that they created this special word for it, and now we use it in science to describe everything from the yellow in autumn maples to the compounds that make daffodils glow. There's something so satisfying about having a fancy, scientific word for sunny yellow — it makes every golden sunset, every field of sunflowers, every pat of butter seem more important and beautiful. It's like giving yellow its PhD!
