From the beginning to the end; the whole thing. The analogy to a complete meal of numerous courses dates back many years. John Heywood’s proverb collection of 1546 has it “from potage to cheese,” and John Clarke’s 1639 collection, “from th’egges to th’apples.” The precise locution of
soup to nuts appears to be American and dates only from the early twentieth century. A very similar cliché,
from start to finish, comes from sports, particularly rowing races. The earliest example in print, according to the
OED, dates from a sports publication of 1868. This cliché is more common in Britain, where
finish is used as a noun more often than it is in America. See also
alpha and omega;
from the word go.
