HCE is referred to by literally thousands of names throughout the book; leading Terence Killeen to argue that in "Finnegans Wake" "naming is [...] a fluid and provisional process". HCE is at first referred to as "Harold or Humphrey Chimpden"; a conflation of these names as "Haromphreyld", and as a consequence of his initials "Here Comes Everybody". These initials lend themselves to phrase after phrase throughout the book; for example, appearing in the book's opening sentence as "Howth Castle and Environs". As the work progresses the names by which he may be referred to become increasingly abstract (such as "Finn MacCool", "Mr. Makeall Gone", or "Mr. Porter").
