more power to you/him/them

Good for you; good luck. This earlier version of right on dates from the mid-nineteenth century. A variant that appeared on both sides of the Atlantic is “More power to your elbow,” an encouragement to drink more, which first appeared in print in 1860 in a letter of James Russell Lowell’s and was repeated by Shaw in John Bull’s Other Island. That version is now obsolete, but the cliché survives.
