An experienced user posted this comment under an answer that cited M-W dictionary.
Btw, MW is the worst, most out-of-date dictionary on the planet!, but GKP regularly sings its virtues in public, and recommends it for students studying English linguistics at Edinburgh. Here is one of his quotes about it: "Merriam-Webster's Dictionary of English Usage, with its 978 pages of brilliant and clearly explained objective scholarship ...". You can read that quote here.
As far as I know M-W is one of the most respectable sources regarding the English/American language, and it is one of the source that ELU recommends as reliable.
Is Merriam-Webster a reliable source or, as the comment suggests, a bad dictionary?
