evolve

An evolve means to change over time, often becoming more complex or developed.

You might use this word when talking about how humans have evolved as a species, or how a baby evolves from crawling to walking. But it's not just limited to living things - you can also talk about how technology has evolved, like how your phone has gotten better and better over the years. You might say that a new idea is evolving in popularity, meaning it's becoming more widely accepted and used. Even languages evolve, with words and phrases changing in meaning or usage as people communicate.
