A person who is undergoing psychoanalysis; a patient of a psychoanalyst.
From French 'analysand,' coined in the early 1900s by combining 'analyse' with the suffix '-and' (one who is treated/acted upon), following the pattern of words like 'multiplicand'.
The word 'analysand' is fascinating because it comes from a mathematical suffix—just as a multiplicand is 'a number to be multiplied,' an analysand is literally 'a person to be analyzed.'
