turn into, become, get, grow, elapse, reach
成 centers on a process of change leading to a result: turning into something, becoming, growing, or reaching a state. The idea of elapsing also fits as time passing until a point is reached.
成 is thought to combine 戊 (a halberd-like weapon) with 丁 (a nail or small stroke), suggesting the idea of completing or finishing something, perhaps originally related to a ritual or action. The exact historical development is uncertain.
The outer shape 戊 looks like a container, and the inner stroke 丁 is like a seed sprouting. Picture something inside a vessel growing and turning into its final form.
For セイ, imagine a seed growing into a plant and you say, 'Say, it became a tree!' The word 'say' cues セイ while the seed reaches its final form.
