The OED is a big book. 20 volumes. It is very in depth and if you wish to understand the English language, it is the source most intellectuals prefer.
However, the OED you get on google is the condensed version.
The REAL OED requires payment. Since I am still in Grad school, I have free access.
Trust me, I would not use these words if I did not know what they meant.
Here's an example of a single OED definition (this is "acting"... if you want, I could all add "act" and "action"):
