This noun denotes suspicions or speculative guesses—thoughts not grounded in evidence but arising from a mistrustful disposition. In 1 Timothy 6:4, Paul lists 'suspicions' among the evil fruits of false teaching that loves controversy: it breeds envy, strife, slander, and baseless suspicions. These are imagined offenses or paranoid conjectures that poison community relationships. The classical usage could mean conjecture or guess; in the New Testament it takes on the negative sense of unfounded, divisive suspicions.
