If you think of the side opposite say angle A in a triangle, then that
side 'SUBTENDS' angle A.  The word is most commonly used for the chord
of a circle, SUBTENDING an angle at the circumference or at the centre
of the circle. You can also think of the arc of a circle subtending an
angle at the centre or at the circumference.  The angle subtended is
'opposite' the chord or arc.
