Definition of semicircular:
Sunset- time had not nearly come yet, but already a silver slit was torn in the blue of the sky; and for the second time the heather moon was smiling its bright semicircular smile, as if to say, " Make the most of me, Barrie, your time is short!"- "The Heather-Moon", C. N. Williamson and A. M. Williamson.
