When a dream, plan, or idea finally comes to fruition, we often say that it becomes a reality. However, there are a variety of other ways to express this concept. Some alternate expressions for "becomes reality" include "manifests," "materializes," "comes to pass," "turns into a truth," "embodies," "actualizes," "realizes," "attains fruition," and "comes to life." Each of these phrases subtly conveys a slightly different shade of meaning, so it is important to choose the one that best suits the context and intent of your writing.
