Questions & Answers about Θέλω να ξεκαθαρίσω ότι είμαι απλώς κουρασμένος.
In Greek, verbs like θέλω (I want), μπορώ (I can), πρέπει (I must) normally take another verb introduced by να.
So θέλω να ξεκαθαρίσω literally is “I want that I (should) clarify”.
The να marks a subordinate verb (subjunctive-type clause). You cannot say ✱θέλω ξεκαθαρίσω; the να is required.
Ξεκαθαρίσω is the aorist subjunctive; ξεκαθαρίζω is present.
- θέλω να ξεκαθαρίσω = “I want to clarify (this) once / make it clear now.”
- θέλω να ξεκαθαρίζω would mean “I want to be clarifying (habitually, repeatedly).”
Because the speaker is talking about one specific act of clarification, the aorist ξεκαθαρίσω is the natural choice.
The form you see (aorist stem) is used both:
- as simple past indicative: ξεκαθάρισα = I clarified
- and as aorist subjunctive: να ξεκαθαρίσω = (that) I clarify (once).
Here, because it follows να, it is subjunctive, not past. Greek reuses the same stem for these two functions; the context (να) tells you which it is.
