Origin of 'meridian'

The word 'meridian' originates from the Middle English 'meridian', which derives from the Old French 'mรฉridien' and further from the Latin 'meridianus', meaning 'midday' or 'noon'. This Latin word comes from 'meridies', meaning 'midday', which itself is a combination of 'medius' (middle) and 'dies' (day). In historical contexts, meridians were significant for understanding the passage of time, as noon was associated with the position of the sun directly overhead at the highest point in the sky. Over time, the term evolved to encompass both geographic lines that denote longitude as well as the concepts of time associated with these lines. The use of the term in scientific and navigation disciplines became prominent during the Age of Exploration when accurate mapping and timekeeping were essential for sea voyages across the globe.
