What dictionary do you use as your source of truth?

I do not view dictionaries as a source of truth, and generally I don't accept a prescriptivist view onlanguage. Dictionaries are for referencing. Reading Xah Lee's reviews of dictionaries made me understand that different ones have different purposes.

"Source of truth"? What the heck does that mean? Truth for whom?

Dictionaries aren't for policing language.

They describe how people use language, not the best and only way to use language.

Oxford English Dictionary.

I like onelook.com -- it's a dictionary gateway site. It searches both general English and specialist dictionaries.

I usually use The Free Dictionary by Farlex.
