Morning

Morning is the period of time between midnight and noon or, more commonly, the interval between sunrise and noon. Morning precedes afternoon, evening, and night in the sequence of a day. Originally, the term referred to sunrise.

The words “morning” and “tomorrow” began in Middle English as morwening, developing into morwen, then morwe, and eventually morrow, before entering Modern English. English uniquely separates “morning” and “tomorrow,” despite their common root. Other languages, like Spanish and German, have one word – mañana and morgen, respectively – to signify both “morning” and “tomorrow."

According to Max Weber (General Economic History pp23), “Morning” takes on another meaning, specifically, “the size of land strip "which an ox could plow in a day without giving out". As such, a “good morning” could mean “a good day’s plow.”

Some languages that use the time of day in greeting have a special greeting for morning, such as the English . The appropriate time to use such greetings, such as whether it may be used between midnight and dawn, depends on the culture's or speaker's concept of morning.

Morning typically encompasses the (mostly menial) prerequisites for full productivity and life in public, such as bathing, eating a meal such as breakfast, dressing, and so on. It may also include information activities, such as planning the day's schedule or reading a morning newspaper. The boundaries of such morning periods are by necessity idiosyncratic, but they are typically considered to have ended on reaching a state of full readiness for the day's productive activity. For some, the word morning may refer to the period immediately following waking up, irrespective of the current time of day. This modern sense of morning is due largely to the worldwide spread of electricity, and the concomitant independence from natural light sources.

The morning period may be a period of enhanced or reduced energy and productivity. The ability of a person to wake up effectively in the morning may be influenced by a gene called "Period 3". This gene comes in two forms, a "long" and a "short" variant. It seems to affect the person's preference for mornings or evenings. People who carry the long variant were over-represented as morning people, while the ones carrying the short variant were evening preference people.
