lag behind

Hi,
Could you take the sentence as valid: “Usually, even the best dictionaries lag behind when it comes to new words (already) circulating for some time among some groups of people.”?

Hi,

It really depends how long ‘lag behind’ indicates. I know from what I have heard that the Oxford English Dictionary has to be satisfied that a ‘new’ word has to have been used a certain number of times in written form before it can be included in the dictionary. I think you have to accept that some words have a very short shelf life and don’t survive long enough to be included in a dictionary.
