Compositional etymology. It is very old and its first occurrence is found in Plato, Cratylus 411d4. However, Plato understands it differently: Ἡ “φρόνησις”· φορᾶς γάρ ἐστι καὶ ῥοῦ νόησις. εἴη δ’ ἂν καὶ ὄνησιν ὑπολαβεῖν φορᾶς· ἀλλ’ οὖν περί γε τὸ φέρεσθαί ἐστιν "Wisdom (φρόνησις); for it is perception (νόησις) of motion (φορᾶς) and flowing (ῥοῦ); or it might be understood as benefit (ὄνησις) of motion (φορᾶς); in either case it has to do with motion." That is to say, in Orion's etymology, which is then repeated in the lexicographical tradition, the head of the compound is "to bring" and the structure is assumed to be verb-object (as in φερέοικος), whereas in Plato's explanation, the head is "benefit", and the structure is assumed to be Genitive-Noun. However, in both cases φρ- is referred to φέρω, as underlined by Plato. Orion's etymology is semantically simple, for indeed wisdom brings benefit to the wise man. The etymon is the produce of the lemma. Plato's explanation is more complex, and the assumed etymon is the noun φορά rather than the verb φέρω, with φορά itself being understood as meaning simply "motion". In both, a syncope is required in the first syllable, yielding φρ- (this is explicit in the Gudianum). Plato's etymology remains isolated
