24 Words that Mean Totally Different Things Now Than They Did Pre-Internet

Technological change, as we know very well, tends to provoke linguistic and cultural change, too. It's the reason why, several times a year, dictionaries trumpet the addition of new and typically very trendy words.

But more interesting than the new words, I think, are the old words that have gotten new meanings: words such as "cloud" and "tablet" and "catfish," with very long pre-Internet histories. The reappropriation is rarely random; in most cases, the original meaning of the word is a metaphor for the new one. Our data is as remote as a cloud, for instance; catfish are just as tricky and unpredictable as an online love interest.

Anyway, this is all a very long way of saying that Dictionary.com's 20th birthday is more interesting than most: To mark the occasion, the online dictionary has compiled a list of words whose meanings have changed since it launched two decades ago. To that list, we have added a few tech terms of our own: such as "troll" and "firehose."

On one hand, the list shows how technology has shaped language over time. But it also shows how language has shaped technology - or, at least, our technological understandings and paradigms. Think about a term such as "cloud": the fact that we picked that to describe cloud computing says a whole lot about how we viewed that technology when it was brand-new. Don't even get me started on words such as "sandbox" and "canoe"...
