American Heritage® Dictionary of the English Language, Fourth Edition
- n. The act or process of transpiring, especially through the stomata of plant tissue or the pores of the skin.
Century Dictionary and Cyclopedia
- n. The act or process of transpiring; especially, exhalation through the skin: as, the transpiration of obstructed fluids.
- n. In botany, the exhalation of watery vapor from the surface of the leaves of plants. A great part of the water which serves as the vehicle of the nutritious substances contained in the sap is disposed of by transpiration. When thus given out it sometimes appears in the form of extremely small drops at the tip of the leaf, and especially at the extremities of the nerves.
Wiktionary
- n. botany The loss of water by evaporation in terrestrial plants, especially through the stomata; accompanied by a corresponding uptake from the roots.
- n. physiology The process of giving off water vapour through the skin or mucous membranes.
- n. The passage of gases through fine tubes.
GNU Webster's 1913
- n. (Physiol.) The act or process of transpiring or excreting in the form of vapor; exhalation, as through the skin or other membranes of the body. Perspiration is a form of transpiration.

- n. (Physics) The passing of gases through fine tubes, porous substances, or the like.

Examples
“The net effect of reduced transpiration is that plants consume less water – meaning more remains in the soil and can run off into rivers.”

“This order shall be effective in any case in which the travel or transpiration is authorized or approved and commenced on or after September 23, 1950.”
“This process, called transpiration, is similar to the human cooling effect of perspiration.”
“Hales conducted hundreds of experiments on plants that demonstrated the flow of sap in the roots and stalks of plants as well as leaf-based evaporation of water (a process known as transpiration).”
“Much of the solar energy that falls on a natural forest is dissipated high in the tree canopy through "transpiration," the evaporation of water transmitted from the soil through the roots, stems, and foliage of plants, a process that consumes solar energy and cools the environment.”
“Abbés Nollet and Menon that animals (cats, pigeons, chaffinches) lose weight when subjected to prolonged electrification, the loss being ascribed to increased "transpiration" under electrical stimulus.”
“In fact, such plantings are helpful because they stabilize the soil surface and don't interfere with soil transpiration.”
“Soil transpiration around a septic system is the movement of oxygen into the soil to aid in the process of breaking down matter and the evaporation of leachate or extra septic moisture.”
“But planting should not be so dense or with a species that will interfere with soil transpiration or evaporation of leachate.”
“Green roofs lower heating costs in cold climates by preventing heat escape from buildings and lower air conditioning costs in warm climates, keeping buildings cool via plant transpiration processes.”
