An archaic verb meaning to seek out thoroughly, search exhaustively, or pursue something from beginning to end.
From 'for-' (completely, thoroughly) + 'seek.' The 'for-' prefix intensifies 'seek' to mean comprehensive or exhaustive searching, a formation common in Old and Middle English.
Medieval texts used 'forseek' when knights went on quests—it suggested not casual looking, but a thorough, dedicated pursuit to the very end.
