The infinitive regularly functions as the object (or complement) of a verb. Hence, they are called complementary infinitives.
The infinitive will be anarthrous. cf. BBG 32.14; GGBB p. 598.
They almost always follow these verbs:
- αρχομαι,
- βουλομαι,
- δυναμαι (always followed by a complementary infinitive),
- επιτρεπω,
- ζητεω,
- θελω,
- μελλω,
- οφειλω.
