Kappa Aorists
Three verbs form the aorist active indicative singular with /κ/, lengthening of the base vowel, and athematic α personal markers. In the plural, they are asigmatic and athematic. These verbs are /δο/, /θε/, and /Jε/, and they conjugate as follows.
δο/ “give”
| Singular | Plural | |
| 1st Person | ἐ/δο/κ/α > ἔδωκα | ἐ/δο/μεν > ἔδομεν |
| 2nd Person | ἐ/δο/κ/ας > ἔδωκας | ἐ/δο/τε > ἔδοτε |
| 3rd Person | ἐ/δο/κ/ε > ἔδωκε | ἐ/δο/σαν > ἔδοσαν |
θε/ “put”
| Singular | Plural | |
| 1st Person | ἐ/θε/κ/α > ἔθηκα | ἐ/θε/μεν > ἔθεμεν |
| 2nd Person | ἐ/θε/κ/ας > ἔθηκας | ἐ/θε/τε > ἔθετε |
| 3rd Person | ἐ/θε/κ/ε > ἔθηκε | ἐ/θε/σαν > ἔθεσαν |
Jε/ “throw”
| Singular | Plural | |
| 1st Person | ἐ/Jε/κ/α > ἕηκα > ἧκα | ἐ/Jε/μεν > εἷμεν |
| 2nd Person | ἐ/Jε/κ/ας > ἕηκας > ἧκας | ἐ/Jε/τε > εἷτε |
| 3rd Person | ἐ/Jε/κ/ε > ἕηκε > ἧκε | ἐ/Jε/σαν > εἷσαν |
Jε/ is a notoriously annoying verb. Because J is a consonant (/y/), the verb uses the ἐ/ past time marker. Then J drops and becomes a rough breathing. The ἐ/ past time marker, then, contracts with the vowel of the base: ἐἡ- (/ehē/) to ἡ- (/hē/) in the singular and ἐἑ- (/ehe/) to εἱ- (/hey/) in the plural. The intermediate forms of the singular (ἕηκα, ἕηκας, and ἕηκε) are found in Homer.
In all other forms, these verbs are normal asigmatic athematic aorists:
δο/τε > δότε (aorist active imperative, second plural)
θε/ντ/ος > θέντος (aorist active participle, genitive singular)
ἐ/Jε/μεθα > εἵμεθα (aorist indicative middle, first plural)
