Still-life with Apples and Oranges by Dezső Czigány, c. 1910
Apples and oranges is a common English idiom. It is used to describe unlike objects or people.[1] One of the most well-known bits of popular wisdom in the English-speaking world is that apples and oranges cannot be compared.[2] The ability to tell apples from oranges is learned.[3]
The phrase is almost always used along with a warning that things in different categories cannot be compared,[4] or that the comparison is improper.[5]
