If there's one thing that dictionary publishers have learned, it's that announcing new words added to their latest editions is good for generating some media attention — and also generating public hand-wringing over what the new entries say about the state of our society and our language.

Take the latest batch to make the grade for Merriam-Webster's Collegiate Dictionary. As in past years, Merriam-Webster has decided on 100 updates to its 2012 edition (some are brand-new entries, while others are expansions of existing ones). Here are 25 of the new entries, as they appear in the dictionary (well, we've censored one entry a little bit):

  • aha moment n (1939) : a moment of sudden realization, inspiration, insight, recognition, or comprehension

  • underwater adj (1672) ... 3 : having, relating to, or being a mortgage loan for which more is owed than the property securing the loan is worth

The Associated Press was first to report on the dictionary update, under the headline "F-bomb makes it into mainstream dictionary." But despite the risque nature of f-bomb, its inclusion in Merriam-Webster hardly signals the end of civil society. In fact, the Merriam lexicographers have taken a somewhat conservative approach to this lexical item. It has already merited admission to dictionaries from American Heritage and Collins, and Oxford English Dictionary editor at large Jesse Sheidlower noted on Twitter that f-bomb has been in the OED since 2008.

Whenever these lists are publicized, the more frivolous or provocative words elicit strong responses. Sometimes those responses can be a bit delayed. For instance, Oxford Dictionaries Online (the hipper cousin of the OED) put out a couple of quarterly updates earlier in the year, but only recently have they attracted much attention, thanks to a post on the popular site Mental Floss (which apparently combined the ODO updates with some from last year's Concise Oxford). Here are some typical responses from Mental Floss readers when confronted with such words as jeggings, whatevs, woot, and noob:

I weep for the English language.

I dont want to live here anymore,... Beam me up Scotty

This can't be true. No. No.

Even if the inclusion of slangy and evanescent terms seems unbecoming for major dictionaries, there's nothing particularly earth-shattering about lexicographers treating these less-than-serious words in a serious way. It's all part of the rich diversity of English, and there's no point in turning up our noses at words that appear to some as improper or unworthy.

What's more, dictionaries are increasingly relying on their own readers for suggestions of new slang and other items that their editors might have missed. To find out about how the U.K.-based Collins English Dictionary is "crowdsourcing" suggestions for new words, check out my latest column in the Boston Globe. There you'll learn the definitions of such novelties as floordrobe, bridezilla, and one of my favorites, mobydickulous. Which words do you think should make the cut and enter the major dictionaries?
