What is the best definition for the word gestate?

The term "gestate" refers specifically to the process of carrying a developing embryo or fetus within the womb, which is closely associated with conception. When something is said to be "gestating," it implies that it is in a stage of development or making progress from an initial idea or concept towards a completion. Therefore, the word "conceive," which means to form or devise (a plan or idea) in the mind, aligns perfectly with the essence of gestation, as both involve the notion of beginning a process that leads to creation or development. This connection to the initial stage of development solidifies "conceive" as the best definition for "gestate."
