As someone with a reputation for excessive use of abbreviations, I am occasionally asked to compose a list of common acronyms and such, making them easier for people to decode. My perennial response is to refuse, pointing out that I’d hate to deprive my correspondent of the opportunity to discover unknown treasures while searching the web.
Similarly, I’m often stumped when being chastised for using (supposedly) big words – which is how cdent came to exclaim the above: Words have meaning and communication is important. Being capable of expressing yourself concisely and understanding subtleties is often crucial; a nuanced vocabulary with a grasp of connotations can be immensely helpful. The most effective way to learn that is through exposure, in which case looking things up is what readers are supposed to do! So pick up that dictionary; be dicurious!
