Odyssey A 56 goes thus:
αἰεὶ δὲ μαλακοῖσι καὶ αἱμυλίοισι λόγοισιν
I find it difficult to scan this verse. The word μᾰλᾰκός has two short syllables, which must be preceded by a long one; and yet δὲ cannot possibly be long. Or can it?
In addition, the beginning of the verse, αἰεὶ, must be two long syllables, which must be followed by a long syllable, and yet it is δὲ that follows.
