Have you ever wondered why ‘Merry Christmas’ Not ‘Happy Christmas’ is used to Wish Christmas (Generally). Is it something to do with Grammar. No Certainly Not, it has nothing to do with Grammar but is with Old habits and Traditions.
“Merry Christmas and a Happy New Year” (thus incorporating two greetings) was in an informal letter written by an English admiral in 1699. The same phrase is contained in the 16th century secular English carol “We Wish You a Merry Christmas,” and the first commercial Christmas card, produced in England in 1843. That Day onward it became a Fashionable Tradition.
It was even used in the 16th century English carol “We Wish You a Merry Christmas.” Merry Christmas certainly became famous, in 1843 with the publication of Charles Dickens’ A Christmas Carol. That same year the phrase also appeared on the first commercially-sold Christmas card.
You know British are royally against it as Queen Elizabeth II preferred “Happy Christmas” over “Merry Christmas”.
Christmas or Christmas Day is an annual festival commemorating the birth of Jesus Christ, observed most commonly on December 25 as a religious and cultural celebration among billions of people around the world.
