Question about o-verbs contraction

Greek Learning Greek
1

Hello,
Hoping somebody can help me here, please.
In a book of mine, as well as the Wiki page, I am seeing the contraction of ο + ῃ becoming ῳ.
However, I noticed in another book I have that they list, in the Subjunctive Middle, this combination becoming οι.

Is this something unique to the Subjunctive mood or is there something I’m missing?

Thanks

The Cambridge Grammar lists the contraction as ο + ῃ = οι, whereas Goodwin lists it as ῳ. Goodwin gives as an example the present subjunctive διδόῃς = διδῷς.

The Cambridge Grammar, however, says that in the case of verbs like δίδωμι, which have versions of the stem with long and short vowels (i.e. διδω and διδο) the long form appears in all forms of the subjunctive. So they analyse it as διδώῃς = διδῷς (see section 12.49). They list ω + ῃ = ῳ in their table of contractions (section 1.63); this combination does not appear in Goodwin’s table.

I haven’t looked at what Smyth says.

In -όω verbs, -όῃ contracts to -οῖ (thanks to the terminal iota of -όῃ). So δηλοῖ 3sing.pres.subj.act. and 2sing.pres.subj.pass.

-μι verbs, however, which normally have no thematic vowel, have one in the subjunctive prior to contraction: διδῷ 3sing.pres. contracted from διδόῃ (Smyth 749, cf. 757) or διδώῃ (Cambridge Grammar, cf. Smyth 757D2). The Attic form, amply attested, is simply διδῷ (e.g. Pl.Gorg.472e ἐὰν διδῷ δίκην καὶ τυγχάνῃ δίκης), aor. δῷ; and this is not only Attic but earlier too.
