Ephemeral is a term of Greek origin (where "ephemeral" means "just for one day") used to designate a situation that lasts very little time. It is the opposite of lasting, permanent.
In general, the term is associated with everything that has character passenger, transitional, fleeting, in short term, which is seen for just a moment.
The ephemerality of life is an expression often used to remember that life is fleeting, and that is why it is imperative that each moment be lived intensely.
In Botany, the term is used to designate flowers that wither on the same day they bloom. It also refers to plants whose life cycle is very short and some bloom more than once a year, others only bloom in years of heavy rain.
The insects of the genus ephemera, which belongs to the Ephemerid family, have this name because they only live for a few hours. They are tiny insects, reaching a maximum of four centimeters and inhabiting the banks of rivers or freshwater places.
Also related to intense rain or melting are ephemeral watercourses, which form lakes, streams, streams or rivers that last only a few days.
In Philosophy, everything that is not relevant, shallow and without foundation is considered ephemeral.
Ephemeral success is related to the short-term success experienced by some artists, usually singers of a single song, actors who perform a only soap opera and then fall by the wayside, or even strangers who see celebrities through social media, but only get one hit momentary.
