What's the origin of the phrase 'Look before you leap'?
The intuitive notion that this phrase derives from the undeniable wisdom of checking a fence before jumping over it on horseback appears to be misguided. Such behaviour is and was common enough amongst riders to have been given a name, that is, 'craning'. Nevertheless, the proverb as first recorded refers specifically to the rashness of leap unpreparedly into marriage. This proverb is first recorded in John Heywood's A dialogue conteinyng the nomber in effect of all the prouerbes in the Englishe tongue, 1546:
And though they seeme wives for you never so fit,
Yet let not harmfull haste so far out run your wit:
But that ye harke to heare all the whole summe
That may please or displease you in time to cumme.
Thus by these lessons ye may learne good cheape
In wedding and all things to looke ere ye leaped
The Miracles brought the idea up to date in 1960 with Smokey Robinson's Shop Around:
Just because you've become a young man, now,
There's still some things that you don't understand, now.
Before you ask some girl for her hand, now,
Keep your freedom for as long as you can, now.
My mama told me, "You better shop around".
