It is clear from the opening distich of poem xiv that Ovid sent the poem to Tuticanus very soon after the composition of xii: 'Haec tibi mittuntur quem sum modo carmine questus / non aptum numeris nomen habere meis'.
The only mention of Tuticanus is at the poem's beginning: Haec tibi mittuntur quem sum modo carmine questus non aptum numeris nomen habere meis, in quibus, excepto quod adhuc utcumque ualemus, nil te praeterea quod iuuet inuenies.
The present poem was written quite shortly after xii, perhaps in AD 16: 'Haec tibi mittuntur quem sum modo carmine questus / non aptum numeris nomen habere meis'.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "aptum" in a variety of sentences. We hope that you will now be able to make sentences using this word.
