Gradualism is when something happens gradually or slowly over time, instead of all at once. For example, if you wanted to learn how to swim, you wouldn't jump into the deep end of the pool. Instead, you would start slowly by getting into the shallow end and learning how to float, then you would move on to more swimming skills. Gradualism can be applied to many things like this; it means taking things one step at a time, rather than trying to do everything at once.
