undermine

1. (figuratively) To weaken or work against; to hinder, sabotage.Examples: "The war efforts were undermined by the constant bickering between the allies."; "The penile mishaps (one involving a bristled toothbrush), severings (one involves hungry ducks) and surgeries cited by Ms. Roach are nothing if not memorable, but her book consistently undermines its own discoveries."; "The growing use of social media to spread anger and dissent in the Arab world has been hailed by western governments as one of the chief justifications for a completely unfettered internet. The US is reportedly funding the secret rollout of technology in Iran in an effort to undermine internet censors in the country."Synonyms: corrode, undercut

2. (philosophy) To regard an object as the sum of the parts that compose it, in object-oriented ontology.Examples: "We can even go further: when we consider an object in everyday life we do not usually just undermine or overmine it as if it demanded an either/or approach, but rather we run the two processes in tandem: duomining, as Harman labels it."
