“Impediments” refer to things that hinder or obstruct progress. Some antonyms for “impediments” are “aids”, “facilitators”, and “boosts”.
“Aids” in this context mean things that help or assist. For example, “Good tools are aids to productivity, rather than impediments.” This shows the contrast between something that promotes progress and something that holds it back.
“Facilitators” are people or things that make an action or process easier. “Skilled negotiators can act as facilitators rather than being impediments to a deal.” Here, facilitators are seen as positive forces that enable progress, in contrast to impediments.
“Boosts” imply an increase or enhancement that propels forward. “Positive feedback can give a boost to confidence, unlike impediments that lower it.” This antonym emphasizes the idea of moving forward and upward rather than being blocked.
