Wayward

The adjective wayward, not often used these days, means 'self-willed', 'perverse', 'going in a direction [or doing something] that is against the wishes of others'. It was extended to mean 'capricious', 'erratic', 'going one's own way'. It was readily used about children.

Etymological note: wayward is a contraction of awayward[s], 'travelling in the other direction', or 'turned in the opposite direction'. (In this, it is akin to 'froward'.) Sir Thomas More used #awayward' in the literal sense: "Our life walketh awai ward, while our death draweth toward [God and heaven]" (Treat. Quatuor Nouissimis in Works, (c.1522), cited in OED), but this is one of the last uses of the word, which hardly survived into Early Modern English. As the aphetic form wayward filled its place, it came to be interpreted as 'wanting {or going] one's own way' - a very different idea from the original.

Froward, untoward and wayward are all, in their different ways, antonyms of toward.
