As a noun, a condition is the state something is in, or a requirement that must be met for something else to happen. As a verb, to condition means to train or prepare someone or something to behave in a certain way.
From Latin 'condiciō', meaning 'agreement, situation, stipulation', from 'condicere' ('to speak together, agree'). It entered English via Old French with both the sense of circumstances and rules.
