The headword phrase must be quoted from somewhere, but it is multiply problematic: here in the Suda qeia/somai o(/lh (for the verb cf. theta 306, theta 307, theta 309), but in Photius, Lexicon theta58 Theodoridis qia/sw| maino/lh| (after correction of the adjective). Photius also gives the gloss not as xarw= manikw=s but xorw=| manikw=| ("in a frenzied dance"). Thus, it seems, the headword phrase involves no verb at all but is a noun plus adjective in the dative singular -- and Clement of Alexandria, Protrepticus 1.2.2.7 has it: qia/sw| maino/lh|.
