to make froward or stubborn; to render unwilling or difficult (archaic).
From en- + froward (from Old English fromward, meaning turned away or contrary, from from + ward). An extremely rare archaic term.
Froward is nearly extinct, but when someone 'enfrowards' another person, they're making them contrary or obstinate—it's the verbal version of old English stubbornness.
