Contraindicate → It is formed from "contra-" (meaning against) and "indicare" (meaning to indicate). The word means to indicate against something, particularly in a medical context where a treatment or procedure is not advisable.
Think of 'against' ('contra-') something being 'indicated' ('indicare') — that's why contraindicate means to indicate that something should not be done.
