Ephemeral things (from Greek εφήμερος – ephemeros, literally "lasting only one day") are transitory, existing only briefly. Typically the term is used to describe objects found in nature (such as some flowers, insects, and diseases) , although it can describe a wide range of things.
An ephemeral waterbody is a wetland, spring, stream, river, pond or lake that only exists for a short period following precipitation or snowmelt. They are not the same as intermittent or seasonal waterbodies, which exist for longer periods, but not all year round.
Many plants are adapted to an ephemeral lifestyle, in which they spend most of the year or longer as seeds before conditions are right for a brief period of growth and reproduction. The spring ephemeral plant mouse-ear cress is a well-known example.
Ephemeral can also be used as an adjective to refer to a fast-deteriorating importance or temporary nature of an object to a person. Brands are notoriously ephemeral assets, magazine publishing was once much more ephemeral than it is today, as was television programming.
A number of art forms can be considered ephemeral because of their temporary nature. Early land art and all sand sculptures, ice sculptures and chalk drawings on footpaths are examples of ephemeral art. G. Augustine Lynas and Duthain Dealbh create ephemeral sculptures.
Often happiness is described as being ephemeral, as one does not find it to be a permanent state, within the scope of human lives. There are always varying shades of happiness and disappointment.

From New Latin ephemerus, from Ancient Greek ἐφήμερος (ephēmeros), the more common form of ἐφημέριος (ephemerios, “of, for, or during the day, living or lasting but for a day, short-lived, temporary”), from ἐπί (epi, “on”) + ἡμέρα (hēmera, “day”).
