In the original 1887 poem, Wednesday's child is loving and giving.Wednesday - the name comes from the Middle English Wednes dei, which is from Old English Wednes daeg, meaning the day of the Germanic god Woden (Wodan) who was a god of the Anglo-Saxons in England until about the 7th century.
Wednes daeg is like the Old Norse Odinsdagr ("Odin's day"), which is an early translation of the Latin dies Mercurii ("Mercury's day"). Though Mercury (the messenger of the gods) and Woden (the king of the Germanic gods) are not equivalent in most regards.
Russian does not use pagan names but instead uses sred'a, meaning "middle," similar to the German Mittwoch. Portuguese uses the word quarta-feira, meaning "fourth day."
