Etymology: Leukocytosis is a medical coinage built from two Greek elements: "leukos", meaning white, and "kytos", meaning hollow vessel or cell, which combined with the suffix "-osis" to denote a condition or abnormal increase. The name describes a state in which the blood carries an unusually high number of white cells. The word is formed the way many clinical terms are, by joining classical roots to describe a newly understood phenomenon, so the ancient Greeks had no notion of it; the vocabulary simply borrowed their building blocks. The plural "leukocytoses" is the form used when referring to several distinct cases or instances of the condition, as in discussions of different causes or episodes. Like most Greek-derived medical nouns ending in "-osis", the plural follows the Greek pattern, which is why the ending changes from "-is" to "-es" rather than taking a regular English "-s".
