It is true, you cannot always trust what you read in magazines, even a magazine like National Geographic. I was sitting at a tire place, getting a nail removed from one of my tires, and reading an old magazine because they featured an article on Greenland. In the article was a tidbit that caught my eye: the expression 'on the lam' comes from the Vikings because it is derived from their verb 'lemja'. Being the word-nerd that I am, I look it up as soon as I get home.
Whoever authored this is wrong. The Oxford Dictionary states that it is of 20th century coinage and origins are unknown. It follows 'lam' in the dictionary which does mean 'thrash, hit with a stick ' from the ON lemja which means to 'beat so as to lame' but there is an asterisk in front of the colloquialism which makes it seem to follow the 'beating' word. A quick check at the Zoega Old Norse dictionary reveals that lemja means 'beating' and not 'fleeing' or 'running'. A good and knowledgeable proof reader would have caught that. I am offering my services. :-) (for a fee, of course)
Another quick look in the Brewer's Guide to Phrase and Fable for thoroughness adds nothing because the expression is not even listed, leading me to think 'on the lam' might be an Americanism.
