1 There are no doubt certain subtle distinctions, particularly of emphasis, in the series τελέω, ἐκτελέω[a], ἀποτελέω, ἐπιτελέω[a], συντελέω[a], and τελειόω[c], but it is not possible to determine with precision the particular distinctions on the basis of existing contexts, though possibly ἐκτελέω and ἀποτελέω emphasize more finality, while ἐπιτελέω[a] may focus upon the resulting purpose.

τελειόω is common in legal papyri = “ execute”: see e.g. P Oxy TIT. 483°° (A.D. 108) τελειῶσαι τὸν χρημα[τισμὸν] ὡς καθήκει, ‘to execute the deed in the proper way” (Edd.), and P Giss I. 34% (A.D. 265-6) éredel[woe]y τὰ νόμιμα. In P Oxy IT. 2389 (A.D. 72) it seems rather to have the meaning “complete” by the insertion of date and signatures— προσέρχεσθαι τοῖς ἀγορανόμοις καὶ τε[λειοῦν] ταύτας (sc. οἰκονομίας) ἐντὸς [.... : see the editors’ note.
