A dependent verb form does not prove completion

A class compares the original Greek examples «Θέλω να διαβάσω το μήνυμα», «Αύριο θα διαβάσω το μήνυμα» and «Χθες διάβασα το μήνυμα». One learner calls every reading completed in the past because the stem looks familiar. Another treats να διαβάσω as an ordinary Ancient Greek infinitive. A third identifies desire, future reference and a past event through the complete forms and time words. The task asks for an explanation of what each sentence establishes. The examples are new classroom sentences, not attributed quotations. No later passage confirms whether the first desired action or second planned action actually occurred. A valid response should distinguish aspectual form from time and avoid importing a different historical Greek system into everyday Modern Greek grammar.
