Notes on the Table of Verb Endings.
§ 50. In the Pres. and Fut. the ο of the 1st sing. act. is contracted (with the union-vowel) into ω, and the σαι of the 2d sing. pass. into ῃ or ει.
§ 51. Signification limits the primary terminations to the Indic. and Subj., and the secondary to the Indic. and Opt.: likewise the Imperf. and Pluperf. to the Indic., and the Imper. to the Pres., the Aorists and (rarely) the Perf.
§ 52. The active terminations are assumed throughout by the Perf. and Pluperf. mid., and the Aorists pass.
§ 53. The terminations of the Imper. are analogous to the secondary in the act., and in the mid. and pass. they are merely the same strengthened, thus: Sing. 2d,--[Aor. pass, ϑι, 1st Aor. act. (σ)ov] (pass. ο [1st Aor. mid. ι] or σο); 3d, τω (pass. σϑω,) Plur. 2d, τε (pass. σϑε); 3d, τωσαν [or contr. ντων] (pass, σϑωσαν. [Dual. 2d, τον (σϑον); 3d, των (σϑων,)]
§ 54. The Infin. in the act. forms ends in εν, [contr., with union-vowel into ειν] (Pres., Fut., and 2d Aor.,) αι, (1st Aor.,) or ναι, (Perf. act. and mid. and both Aor. pass.;) elsewhere in σϑαι.
§ 55. In the Participles the stem ends in ντ in the act. forms, (except the Perf. act. and mid., which have ότ;) the rest take μεν, (Perf. pass, μέν.) These latter are [masc. and neut.] of the second declension, the others of the third.
