An adjective meaning cold in temperature, used both literally and as a vivid metaphor for spiritual condition. In Matthew 10:42 Jesus promises reward to anyone who gives a cup of cold water to a little one -- a simple, refreshing act of kindness. In Revelation 3:15-16 the risen Christ addresses Laodicea with the famous words: 'you are neither cold nor hot.' Here psychros, paradoxically, would be preferable to the tepid middle ground, suggesting that even outright coldness has a bracing honesty that lukewarmness lacks. German kalt, Spanish frío, and French froid all map directly to the temperature sense.
