Like others, I also struggled with 14, and came here for help in the parsing. From what others have said I assume it must be:
- take a five letter word for what Everyman is an example of
- the "I" and the "S then are removed ("is going")
- then add an "S" (speechify opening)
Seems strange to rmeove an "S" then add one back, but that's all I can think of
