Newbie to Greek here, I have a question about compensatory vowel lengthening:
"5. The Severer (and earlier) Doric contracts εε to η, and οε, οο to ω. Thus, φιλήτω from φιλεέτω, δηλῶτε from δηλόετε, ἵππω from ἵππο-ο (230 D.); the Milder (and later) Doric and N. W. Greek contract to ει, and ου. Aeolic agrees with the Severer Doric." - H.W. Smyth, Greek Grammar
Does Koine Greek align with severer Doric in contracting εε to η, or does it align with milder Doric in contracting εε to ει?
Strong's Concordance attests the name Φίλητος, which I think is contracted from φιλεέτω as cited by Smyth? Could this suggest the contraction adopted was εε to η, or would we perhaps expected regional varieties?
