The opposite of giving a boost to something would be to hinder or impede it. This could happen through neglect, lack of support, or even direct opposition. Other antonyms include hindering, suppressing, limiting, and weakening. When we hinder progress or growth, we prevent something from reaching its full potential. This can be a result of personal biases or misconceptions, or larger societal forces that keep certain groups from flourishing. Making a concerted effort to recognize and overcome these roadblocks is essential if we want to create a more inclusive and equitable world.
