What does opportunistic mean?
Opportunistic describes conduct, decisions, or situations shaped by whatever advantage is immediately available. In everyday use, the word often implies that someone is taking advantage of circumstances for personal or organizational benefit without considering longer-term consequences, principles, or the effects on others. Calling an action opportunistic therefore tends to be mildly critical, suggesting flexibility or expediency rather than a stable commitment. The adjective can also be used more neutrally in fields such as medicine, biology, and strategy to describe actions that respond to favorable conditions. A person who behaves in this way may be called an opportunist, and the associated practice is opportunism. Although opportunity can simply mean a favorable chance, opportunistic emphasizes how that chance is used rather than the chance itself.
