[1] The headword is present active participle of e)palei/fw, masculine nominative singular. Same or similar glossing in Hesychius and other lexica; evidently quoted from somewhere (and see under upsilon 500).
[2] Here the verb appears in the pluperfect middle-passive, third person singular (with neuter plural subject). The quotation, also in ps.-Zonaras, is unidentifiable. For tin, see kappa 457; for helmets, kappa 2325.
