The British National Corpus (BNC) is a 100 million word collection of samples of written and spoken language from a wide range of sources, designed to represent a wide cross-section of current British English, both spoken and written. You can use it to search for word frequencies and also examples of how a particular word is being used.
The Compact Oxford English Dictionary of Current English contains 145,000 words, phrases, and definitions.
If it’s new, obnoxious, profane, and slang, it’s in the Urban Dictionary. The ultimate vox pop dictionary where a word’s definition is voted for. These are “words for the moment” and most are hilarious!
If there’s a collective noun for a group of linguists, it should be found here. The Language Log might best be described as “linguists at play” and the topics covered are boundless. The Word Guy aspires to be listed as a contributor but he know his limitations.
My “real job” is as a Speech-Language Therapist working in the field of Augmentative and Alternative technology. The QUAD is a profile I designed for “QUick And Dirty” analysis of a language sample generated by an AAC device. It’s here because I can have a permanent location where folks can download it. If you are not working in AAC, it’s probably of zero value to you
Another “real job” resource. Here is a free manual board based on the “WordCore” software I wrote, which provides lots of high frequency core words and a QWERTY keyboard. Download it, laminate it, and use it as you wish.
The Etymologized “Kubla Khan”
Poetry and Etymology in one. A free download of Samuel Taylor Coleridge’s classic poem with notes on word origins.
