Languagle #1: Malayalam
അടിതെറ്റിയാൽ ആനയും വീഴും
Adi thettiyal aanayum veezhum
"Even an elephant falls if it puts a foot wrong."
What it means
Used to say that a single moment of carelessness can bring down even the strongest or most capable, since the elephant, the biggest and most sure-footed animal around, is the image chosen specifically because it should be the last thing to trip.
What kind of saying it is
Oral tradition. In Malayalam, a പഴഞ്ചൊല്ല്. Passed down by word of mouth. Sayings like this have no single author.
