Adjectives That Start With "Xanth"

The Greek root "xanth" means "yellow," so any time you see it in a word, it probably has something to do with the color.

  • xanthic - yellow or yellowish; of or having to do with the compound xanthine
  • xanthous - yellow in color; relating to people with yellowish, auburn or light brown hair

Adjectives That Start With "Xen"

"Xen" means "foreign," so the following adjectives all have to do with strange, foreign, unnatural or non-native things.

  • xenogenic - originating outside the organism or from a foreign substance introduced into the organism
  • xenolithic - of or pertaining to a rock fragment foreign to the igneous rock in which it is embedded
  • xenophobic - unreasonably afraid of foreigners or strangers
  • xenotropic - replicating or reproducing only in cells other than those of the host species

What would the English language be without a couple quirks? In the examples below, both of the words start with "xen," but they actually mean the opposite of foreign.

  • xenial - a friendly relationship between host and guest
  • xenodochial - friendly to strangers

Adjectives That Start With "Xer"

"Xer" means "dry." Adjectives based on the root "xer" refer to dryness in some way. Although dryness isn't necessarily what you think of when you make copies on a Xerox machine, the origin of the word is the same. In the 1930s, a New York patent attorney wanted to find a way to make copies that didn't involve chemicals (as was required for photography back then). In the end, photocopying (or xerography) became an electrical process, not a chemical one. So, xerography translates to "dry writing," making photocopying a dry process. Pretty cool, right?

  • xeric - adapted to a dry environment
  • xerographic - pertaining to xerography (photocopying)
  • xerophilous - capable of thriving in a hot, dry climate, as certain plants and animals
  • xerophthalmic - pertaining to abnormal dryness of the eyeball characterized by conjunctivitis, a deficiency of tears
  • xerophytic - pertaining to a plant adapted for growth under dry conditions
  • xerothermic - pertaining to a hot and dry climatic period, as one of the postglacial periods
  • xerotic - dry; affected with or characterized by xerosis

Adjectives That Start With"Xyl"

"Xyl" means "wood," so all of the following adjectives have something to do with wood. Here's where everyone's favorite X word (noun), xylophone, comes in. Xylophones today can be made of metal or fiberglass, as well as wood, but the word itself is derived from the fact that xylophones were originally made out of wooden bars of various lengths.

Check out these "xyl" adjectives:

  • xylographic - pertaining to the art of engraving on wood
  • xyloid - of or like wood; woody
  • xylophagous - eating, boring into, or destroying wood
  • xylophonic - pertaining to the sound made by a xylophone
  • xylotomous - capable of cutting or boring into wood
