<P> The Modern English words "morning" and "tomorrow" began in Middle English as morwening, developing into morwen, then morwe, and eventually morrow . English, unlike some other languages, has separate terms for "morning" and "tomorrow", despite their common root . Other languages, like Spanish and German, may use a single word--mañana and Morgen, respectively--to signify both "morning" and "tomorrow". </P> <P> According to Max Weber (General Economic History pp23), the German word Morgen also 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". </P> <P> Some languages that use the time of day in greeting have a special greeting for morning, such as the English good morning . 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 . </P> <P> 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 . </P>
