RHMA, at least in one of its most common uses, refers to a spoken word or
phrase, but I don't find any reason to connect LOGOS with the written word.
There are occassions, in fact, when it clearly seems to refer to spoken words,
as in Jn 4.41: And because of his LOGON, many more believed.
As a general rule, I would be skeptical of any attempt to render a
basic or core meaning to LOGOS. It can be used in many ways, and it often is
pregnant with connotations drawn from Classical or Hellenistics philosophers,
Hebrew scriptures, etc.
