Why was clemency trending last week?
Old English cenning "procreation; declaration in court," present participle of ken (v.). From early 14c. in senses "sign, token; teaching, instruction;" c.1400 as "mental cognition." From 1883 as "periphrastic expression in early Germanic poetry;" in this sense it probably is from Old Norse cognate verb kenna "to know, to recognize, to feel or perceive; to call, to name (in a formal poetic metaphor)."
