Quick answer
Mahjong means sparrow. The name comes from ma que, a Chinese name for the game, and one explanation is that shuffled tiles clatter like sparrows squabbling over crumbs. The game dates from the mid to late 1800s, with the earliest known sets from the 1870s, so the story that Confucius invented it is 1920s marketing. The American game took its shape in the 1930s and added joker tiles in 1961.
What does the word mean, and how old is the game? In short, the name means sparrow, the earliest known sets date from the 1870s, and the story of an ancient origin began as 1920s marketing. The American game is younger still, shaped by its players in the 1930s and given joker tiles in 1961.
The name means sparrow
Mahjong comes from ma que, a Chinese name for the game that translates as sparrow (mah cheuk in Cantonese). In the earliest writings about the game, from the 1890s, it went by several names, among them chung fa and ma que, and the name mahjong was not used until the early 1900s.
Joseph Park Babcock wrote the name as Mah-Jongg when he introduced the game to the United States in 1920, and he trademarked that spelling. Rival makers could not use it, so they sold the game under other names, and within a couple of years the generic mahjong had taken hold. That is why English has both mahjong and the National Mah Jongg League's mah jongg.
One explanation for the name is the sound. Shuffled face down, the tiles make a clatter said to resemble sparrows squabbling over scattered crumbs. Another theory traces the name to an older card game, madiao, so the sparrow story may have been attached afterwards.
How old the game actually is
The game as it is played today was created in the mid to late 1800s, drawing on older Chinese card games played with money suits. The earliest known sets date from the 1870s and the earliest written description of play from the 1890s. Early surviving sets were acquired in Ningbo, Shanghai and Fuzhou, and a 1914 guidebook placed the game's birth in Ningbo about thirty years before. The precise origin is still debated.
That makes mahjong a young game, about a hundred and fifty years old, and the American version still changes every year when the League issues a new card.
The Confucius story is marketing, not history
You may read that Confucius invented mahjong. It is not true. Confucius lived in the sixth and fifth centuries BC, and the earliest known sets date from the 1870s, more than two thousand years later, with no evidence connecting the two.
The story dates from the 1920s, when mahjong first became popular around the world and an ancient, mysterious origin helped sell sets.
How it reached America
Joseph Park Babcock, a Standard Oil representative in China, simplified the rules for English-speaking players. His Rules of Mah-Jongg, known as the red book, appeared in 1920, and that same edition introduced English index numbers on the tiles so players could read them without knowing Chinese characters. The small numbers on Western tiles go back to him.
Abercrombie and Fitch was selling sets in the United States from 1920, and by 1923 Babcock was importing them in great numbers. Mahjong became intensely popular in the early 1920s, and because Babcock held the Mah-Jongg trademark, other companies sold their own sets and books under names such as Pung Chow and Ma Chiang.
Why the American game looks different
The American game took its own shape in the 1930s, through changes women players made to it. They dropped chows, the runs of consecutive tiles that Chinese games allow, limited the hands to the groups listed on a card, and changed how the flowers were used. Those changes became official when the National Mah Jongg League was founded in New York in 1937, and the League still issues a new card every year.
Jokers came later. Until 1961 the American game had no joker tiles, and the flowers were wild instead. Joker tiles arrived in 1961, and the count settled at eight jokers and eight flowers with the 1971-72 card. Some early Chinese sets had wild tiles too, so the idea was not new, but the joker rules American players learn today are the League's own.
The Charleston, the passing of tiles before play, shares its name with a dance of the 1920s, the decade mahjong first became a craze.
Why any of this helps at the table
Knowing the game is young explains its shape. The hands come from a card the League replaces every year, the jokers arrived in 1961 with rules the League set, and none of it is ancient tradition.
It also sets a fair expectation for learning. You are not decoding something mystical. You are learning to match your tiles to the hands printed on a card.
