Greek

Verb

δει • ‎(dei)

1. Aorist infinitive of  βλέπω ‎(vlépo).
2. third-person singular dependent of βλέπω ‎(vlépo)

Usage note: the dependent form (also called the perfective non-past, perfective infinitive or aorist subjunctive) is not used independently, but is used with the particle θα ‎(tha) to form the future simple or perfective future tense; with να ‎(na) to form the subjunctive; and so on.
