[f. BOW sb.1]
1. A Bay-window segmentally curved on plan; called in A. P. S. Dict. Arch., a Bow Bay-window.
Often used as co-extensive with bay-window, whence such absurdities of diction as square bow windows. Bay-window is generic, bow-window specific, and of much later rise, this form of bay being rare in earlier times.
