tō- as a verbal prefix has nothing to do with the preposition tō (which occurs in tō·gædre, 'together,' &c.), but signifies 'separation,' as in tō·berstan (burst asunder), tō·breġdan (shake off), and hence 'destruction,' as in tō·cwīesan (crush to pieces, bruise).
un- negatives, as in un-ġesǣliġ (unhappy).
