Here's a stirring Boston Globe op-ed from master lexicographer Erin McKean, presenting the humane case for a dynamic English language in which speakers are allowed to coin neologisms and new usages without grammar tightasses insisting that language is not a user-modifiable technology .
Whenever I see "not a real word" used to stigmatize what is (usually) a perfectly cromulent word, I wonder why the writer felt the need to hang a big sign reading "I am not confident about my writing" on it. What do they imagine the penalty is for using an "unreal" word? A ticket from the Dictionary Police? The revocation (as the joke goes) of your poetic license? A public shaming by William Safire? The irony is that most of these words, without the disclaimer, would pass unnoticed by the majority of readers. (In case you noticed cromulent, that was invented in the 1990s for "The Simpsons.") Writers who hedge their use of unfamiliar, infrequent, or informal words with "I know that's not a real word," hoping to distance themselves from criticism, run the risk of creating doubt where perhaps none would have naturally arisen.Chillax (via Oblomovka)
