The practice of making the most of situations to gain an advantage, often without thinking about the long-term effects or moral principles.
His opportunism in business led him to make quick decisions that sometimes backfired.
Opportunism is formed from "opportunus" (meaning favorable or suitable) and the suffix "-ism" (indicating a practice or philosophy). The word describes a practice of taking advantage of favorable circumstances for personal gain.
Think of 'favorable' ('opportunus') situations that someone takes advantage of — that's what opportunism means.
