In Reply to: Bank on it posted by jdharris on September 03, 2002
: I'm looking for the origin of the phrase "don't bank on it" or "you can bank on it."
This phrase always makes me think of Robert Blake in "Baretta": "and you can take that to the bank".
From The American Heritage Dictionary of the English Language: Fourth Edition:
PHRASAL VERB: bank on To have confidence in; rely on.
ETYMOLOGY: Middle English "banke", from French "banque", from Old Italian "banca", bench, moneychanger's table, from Old High German "banc".
That leads me to believe the original meaning may have had nothing to do with faith in banking establishments and the idea of a the bench literally being "something you can count on".
