Synonym discussion

Sense: adjective/1

The basic colour sense of green (adjective/1) describes something the colour of grass or leaves. Greenish means 'slightly green' and is used when the colour is not fully or intensely green — a greenish-yellow apple, for example. Verdant is a formal or literary word used almost exclusively for landscapes thick with healthy green vegetation: 'the verdant hills of Tuscany'. Lush adds the idea of rich, thick growth: lush grass grows densely and looks well-watered. Emerald describes a bright, clear, rich green, like the gemstone — often used for eyes, seas, or lawns in descriptive writing. Olive is a dull, yellowish-green, named after the fruit; it describes a subdued, earthy green tone rather than vivid plant-green. For everyday learners: use green for most situations, greenish when something is not fully green, and save verdant and emerald for descriptive or literary contexts.

Etymology

Proto-GermanicOld EnglishMiddle EnglishEnglish

Green traces back to Old English grēne, from the same ancient root as grōwan (to grow — since the colour of living plants was its original reference point). This Germanic root *grō- (to grow, to become green) is shared by Dutch groen, German grün, and Danish/Norwegian grøn. The meaning 'inexperienced' (of a person) appeared by the 1500s, based on the idea of something 'young, fresh, unripe'. The expression 'green with envy' (associating jealousy with a sickly green complexion) goes back to Shakespeare's time, when paleness and greenish skin were linked to the emotion of envy. The modern political and environmental senses (a 'green' party or policy) date from the 1970s–80s, growing out of the earlier association of green with nature and ecological movements.
