I had occasion today to look up the word "syntonics", which apparently has to do with
"emotional responsiveness to the environment." Cool.
Now, I'm currently de-bracketing
...And The Kitchen Sink. Which means I'm looking up a lot of words to find a more alliterative or less repetitious way to say something, but I'm also occasionally trying to look up the word for a concept that I know there has to be a word for. And often as not, I'm not having a lot of luck with that latter.
Which is not surprising, because if you Google "emotional responsiveness to the environment" or even "word for emotional responsiveness to the environment", one thing you won't see in your search results in "syntonics". Emotion, yes; emotional responsiveness of certain population groups, yes; even the emotional impact of nice furniture. But not the one word that embodies the concept, which is what as a writer I'm generally looking for.
That is why a thesaurus, while an invaluable tool, is also sometimes frustrating. And that is why the Internet, while a fine thing, is no substitute for knowing stuff.
