(I) By the relative pronouns οἷος, ὅσος, or by the relative adverb ὡς in exclamations of wonder. The sentences introduced by these words are commonly associated with vocatives or interjections. Cp. 340.
οἷα ποιεῖς, ὦ ἑταῖρε

c. Cp. 2647 for such sentences as οἵᾱν ἔχιδναν τήνδ᾽ ἔφῡσας

d. οἴμ᾽ ὡς is common in expressions of impatience, anger, pity, grief, or fear; as οἴμ᾽ ὡς καταγελᾷς
ah me, how you mock me! Nub. 1238, οἴμ᾽ ὡς ἔοικας ὀψὲ τὴν δίκην ἰδεῖν
