More or less.

   "An abbrev table is represented as an obarray containing a symbol for
    each abbreviation. The symbol's name is the abbreviation; its value
    is the expansion; its function definition is the hook function to do
    the expansion; its property list cell typically contains various
    additional properties such as the use count, the number of times the
    abbreviation has been expanded, or whether the abbrev is a so-called
    "system" abbrev defined by a major mode rather than by the user."
