Supper is the evening meal - ordinarily the last meal of the day.
The term is derived from the French souper, which is still used for this meal in Quebec French and sometimes in Belgian French. It is related to soup.
In some agricultural regions of Canada and the United States, farmers traditionally used "dinner" for a main meal taken at midday, with "supper" being a lighter meal in the early evening. However, this usage is dying out.
The word "supper" is nowadays used almost always as a synonym for "dinner".
In Australian English, supper may refer to a late light dessert had some time after dinner.
In Spain, Portugal and Latin America, supper may be eaten as late as ten or eleven p.m.
