Lunch is an abbreviation of luncheon, meaning a midday meal. In English-speaking countries during the eighteenth century what was originally called “dinner”— a word still sometimes used to mean a noontime meal in the British Isles, and in parts of the United States and Canada — was moved by stages later in the day and came in the course of the nineteenth century to be eaten at night, replacing the light meal called supper, which was delayed by the upper class to midnight.

The abbreviation lunch, in use from 1823, is taken from the more formal “luncheon”, which the OED reports from 1580, as a word for a meal that was inserted between more substantial meals.

Both Etymonline and the American Heritage Dictionary tell … that the word lunch is an abbreviation of the word luncheon. But the Oxford English Dictionary isn’t so sure. This seems to be one of those words that poured into the language during Shakespeare’s lifetime, except it isn’t one that was built on Latin or Greek roots. No one is completely sure where it came from. The word luncheon certainly appears first in the written record, but the OED points out other words like punch and puncheon and trunch and truncheon that were also kicking around at the time. They speculate that while lunch might be short for luncheon, it’s also possible that luncheon was an extension to lunch.

At their first appearance both words, lunch and luncheon hold a meaning a little different than what we understand them to mean today. The OED connects lunch to the word lump because at first a lunch was a chunk of food. A lunch of bacon was a “thick slice of bacon”, not a “meal of bacon.” It was not until about 300 years ago that luncheon started to mean what we think it means today, and then by the early 1800s began to appear again as lunch with that meaning. When it did, lunch was seen as a really trendy word and as such looked down on by some.

No one did. The word was rather created, not invented. Prolly the Brits did.
