Derivational etymology, meant to account for the lines where θεσπέσιος simply means "divine" and not specifically "spoken by a god". Whether this etymology goes back to Apion as the compositional etymology mentioned first is unclear. The second etymology can be an additional remark by Apollonius. The opposition between a compositional etymology for the proper meaning and a derivational etymology for the metaphoric meaning of the same word is also found for κελαινεφής, and for the latter it probably goes back to Aristarchus (see κελαινεφής / κελαινός). The double etymology of θεσπέσιος could go back to Aristarchus, too. As a derivative, θεσπέσιος is etymologized by its synonym θεῖος
