*† ἀν-έλεος, -ον (Attic ἀνηλεής, ἀνελεήμων; MM, VGT, s.v.), merciless: Ja 2:13.†
Moulton & Milligan — Vocabulary of the Greek NT
ἀνέλεος. This remade form in Jas 2.3 may be illustrated from P Lips I. 39% (a.p. 390) τύψας pe [av]eXeHs—though, of course, thus accented, it comes from ἀνελεής. Whether this last is any better Attic than ἀνέλεος may, however, be questioned, unless we postulate it as the alternative to νηλεής, from which the Attic ἀνηλεής came by mixture. But the solitary grammarian whom Lobeck (Péryn., p. 710 f.) quotes for it is not very solid ground
