ようになる

ようになる describes a change of state or development over time. It indicates that someone or something has transitioned from not being in a certain state to being in that state, often as a result of effort, change in circumstance, or aging. It is commonly used for new abilities, new conditions, or a change in appearance or behavior. It contrasts with ている, which describes a current ongoing state, and with れる/られる indicating potential or passive. Typical contexts include skills, abilities, or states that were not present before and have now been attained.
