The noun κινδυνος (kindunos) means danger or hazard. It's unclear where this word comes from. Spiros Zodhiates (The Complete Wordstudy Dictionary) suggests it might stem from the verb κινεω (kineo), to set in motion, but that appears to be unlikely. More likely is a pre-Greek origin, and perhaps even a Semitic one. Here at Abarim Publications we can't help notice the similarity with the verbs נדד (nadad), to retreat or flee, and נדה (nada), to exclude.

The prefix כ (ke), means as if or like; in Leviticus 12:5 occurs the phrase כנדת (kenudat), meaning like a being sick, from the verb דוה (dawa), to be ill or to have a bodily discharge. Since bodily discharge was often indicative of a contagious disease, contact with such fluids was to be avoided like the plague, so to speak.
