Hmmm, this works for me! Thanks a lot, I'll pass it on to my son.
: : My 12 year old was asking me today why we say to be somewhere at something o'clock sharp.
: Sharp - adjective. Probably before 1200 "scharp"; developed from Old English (before 830) "scearp" cutting, keen, sharp.The use of "sharp" as an adjective to mean "promptly, exactly" was first recorded in 1840, ...: It doesn't have anymore information about the evolution of the term. But it would seem to be an easy jump from meaning (c & d, from Merriam-Webster online) clear and distinct to "promptly, exactly."
