I am trying to invent a word by taking an existing word and turning it into a noun a person can be called who is interacting with an object. The trouble I ran into was the initial word's ending.
Since 'message' ends in an 'e', does the new word become messager, messageer, messagor, messageor or something completely different? What would be most consistant with how similar words have originated? I know the word messenger exist, but it does not quite fit what I am looking for. This came up in the context of coining appropriate names for objects invented using a programming language. The new word is supposed to convey that a person can interact with a message (send it, receive one....)
