It's often used in the formation of verbs, particularly those indicating a process of change or development. Here are some examples:
* Acquiesce: To agree passively, to submit.
* Coalesce: To come together and form one mass.
* Effervesce: To bubble up and fizz.
* Emerge: To come out into view.
* Obscene: Offensive, indecent (originally meant "to grow off the stage" in ancient Roman theatre).
* Rescind: To cancel or revoke.
The presence of "esce" indicates that the verb describes a gradual process or transition.
