3.  My statement, then, is this.  That which is spoken of in a special and peculiar manner is indicated by the name of the hypostasis.  Suppose we say “a man.”  The indefinite meaning of the word strikes a certain vague sense upon the ears.  The nature is indicated, but what subsists and is specially and peculiarly indicated by the name is not made plain.  Suppose we say “Paul.”  We set forth, by what is indicated by the name, the nature subsisting. ὑφεστῶσαν. ὑπόστασις is derivatively that which “stands under” or subsists, ὃ ὑφέστηκε.  cf. my note on Theodoret, p. 36.
