"Silent curse" is a phrase that describes a negative thought or feeling that is kept hidden or unspoken. There are a number of synonyms for this phrase, such as "unspoken resentment," "covert anger," "latent frustration," "hidden disdain," "unvoiced bitterness," or "unexpressed animosity." These terms all imply a deep-seated negative emotion that is not being openly acknowledged or addressed, and which may build up over time without any outward expression. Whether in personal relationships or in larger social or political contexts, silent curses can have a corrosive effect on both individuals and groups, leading to ongoing tension, conflict, and a lack of resolution or healing.
