OED Online. You will want this for investigations

Get the OED online access. Thanks to Nevins English Language blog for this. This is really easy, and it is free! 1. Get a library card from your local library(but not now Friern Barnet Library) 2. Click on this link here. 3. Click on the 'Sign in' tab on the top right hand corner 4. Enter your library card number - it will have a letter at the start, and then have 8 numbers. Older cards have a letter, then 10 numbers - so just enter the letter then the first 8 numbers 5. Enjoy all the etymology you could ever need! Trust me, you'll be visiting this post again and again come investigation time.
