FWIW, angel is from Greek αγγελος (angelos) the translation of Hebrew מַלְאַךְ (mal'akh) 'messenger'. The word for fishhook, which occurs in other languages (e.g., Old High German ango, angul 'fishhook, spine, barb', Old Irish cath 'fishhook') is from PIE *ank- 'to bend, curve' (IEW pp.45f.), and which is related to Latin angulus 'angle, corner, nook', Greek αγκυλος (ankulos) 'bent', αγκυρα (ankura) 'anchor'.
