The etymology is given in a list of "adjunction" of extra sounds at the beginning of a word, either vowels or consonants. Whereas most instances involving the adjunction of a vowel reflect real etymological relationships valid from our modern point of view, most instances involving the adjunction of a consonant are incorrect etymologies for modern linguists, but show how the Greeks perceived not only a formal, but also a semantic affinity between the two words thus paired: in fact οὖρος means "favorable", and has nothing to do with θοῦρος "impetuous, fiery", but οὖρος is used mainly as an epithet of wind, and the two words share the notion of a quick move forward. The last pair in the list etymologizes δαίμων, a usual word in all Greek dialects, by a Homeric hapax αἵμων (αἵμονα θήρης, Il. 5.29), the meaning of which was disputed in Antiquity but which most commentators of Homer understood as "skilled, knowing". The god would therefore be the knowing one – as in Plato's etymology of δαίμων by δαήμων. The difference of status between the word δαίμων, usual, and the etymon αἵμων, rare and poetic, was not taken into account. The etymology is reversible: Philoxenus (fr. 466) derives αἵμων from δαίμων (repeated in Orion and the Byzantine Etymologica) (see αἵμων / δαίμων): this accounts for the difference of status, as the poetic word is the one which suffered the alteration
