2. (archaic) Of or pertaining to something not human.Examples: "And then, it may be, of his wish to roam Repented he, but in his bosom slept The silent thought, nor from his lips did come One word of wail, whilst others sate and wept, And to the reckless gales unmanly moaning kept."; "I had bought a toy in the street for my own amusement.

The unmanly chuckle always came, I found, when the poor lady dropped her babe, […]"archaic

3.
