English is 'easy' for foreigners to stumble their way through because of its lack of coherent rules. Likewise, it is easy to create problems of understanding even when following the modern rules because the old rules have long been forgotten.
Exempli gratia: 'froward'
'Once upon a time, in the days of Middle English, froward and toward were opposites. Froward meant "moving or facing away from something or someone;" toward meant "moving or facing in the direction of something or someone." (The suffix -ward is from Old English -weard, meaning "moving, tending, facing.") Froward also meant "difficult to deal with, perverse"; toward meant "willing, compliant, obliging." Each went its own way in the end: froward lost its "away from" sense as long ago as the 16th century and the "willing" sense of toward disappeared in the 18th century. A third relative, untoward, developed in the 15th century as a synonym for froward in its "unruly or intractable" sense, and later developed other meanings, including "improper or indecorous."'
