This is the future middle of teu/xw, governing the genitive of the object aimed at, met, achieved or hit (Smyth, Greek Grammar §§1349, 1350, 1353). For its place in the ancient paradigm of that verb see tau 435 at length. It should be taken as a future of intention (Chantraine, Gr. hom. 440-41), with the middle to express benefit for the subject, in the same way that feu/comai, from feu/gw, e)/fugon, means 'I intend to escape' as distinct from present 'I am trying to escape, am running away' and aorist 'I escaped'. Because of this, its compounds are sometimes glossed in the Suda by the aorist subjunctive (pi 1321, sigma 1639). It is assigned in modern dictionaries to the paradigm of tugxa/nw.
