The term 'in future' can be expressed in two ways: 'HEREAFTER' (9 letters) and 'HENCEFORTH' (10 letters). Both words refer to a time that is yet to come, and are often used to express the idea of something happening from this point forward. 'HEREAFTER' is more commonly used to refer to a specific event or situation that will occur in the future, while 'HENCEFORTH' is more often used to refer to a general pattern or trend that will continue into the future.
