Definition of the word today

The word "today" has its roots in Old English. The Oxford English Dictionary dates the origin of "today" to around the 9th century. It is derived from the Old English words "to" (meaning "at" or "in") and "dæg" (meaning "day"). Initially, the phrase "tō dæg" meant "at the day", which later evolved into "tōdæg", and eventually, the modern English word "today". In Old English, the phrase "tō dæg" was used to indicate a time span, rather than a specific point in time. It was only used in conjunction with other words to specify a particular day, such as "tōdæg þis" (meaning "at this day"). Over time, the phrase became simplified to "today", and its meaning shifted to indicate a specific point in time, rather than a time span.
