if I have apples and oranges, what do i have?

Answer 1

A comparison of apples and oranges occurs when two items or groups of items are compared that cannot be practically compared. The idiom, comparing apples and oranges, refers to the apparent differences between items which are popularly thought to be incomparable or incommensurable, such as apples and oranges.

It is said that the idiom "apples to oranges" first known as "apples to oysters" in John Ray's proverb collection of 1670. The original expression referred to oysters on behalf of oranges as something which can never be compared with the apples.

Moreover, Spanish use it as "apples to pears" while the French use is as "apples to oranges." The exact form of the idiom "apples to oranges" is being used since about 1889.
