vegetation

Etymology

Borrowed from Middle French végétation.

noun

1. (uncountable) Plants, taken collectively.
   As towns continue to grow, replanting vegetation has become a form of urban utopia and green roofs are spreading fast. Last year 1m square metres of plant-covered roofing was built in France, as much as in the US, and 10 times more than in Germany, the pioneer in this field. In Paris 22 hectares of roof have been planted, out of a potential total of 80 hectares. 2013-05-10, Audrey Garric, “Urban canopies let nature bloom”, in The Guardian Weekly, volume 188, number 22, page 30
   There were large amounts of vegetation in the forest.
2. (pathology, countable) An abnormal verrucous or fibrinous growth
3. The act or process of vegetating, or growing as a plant does; vegetable growth.
