I have always found it a sore trial of my faith to regard suam ipsam as = suam dominant, and can only join ipsam with matrem. This leaves suam stand alone, as = suam dominam. That use is doubtless defensible of a wife or mistress in the case of a lover; but it is hardly possible of a sparrow, to whom the lady does not ‘belong’ in that relation. That one who is not lover or husband may know suos is no proof that he may know suum or suam alone.
