What is your preferred online dictionary and why?
My go-to online dictionary has been m-w.com for years, though occasionally the word I’m searching for is obscure enough that you have to be a subscriber to see it. I recently stumbled across thefreedictionary.com and found that in some ways, the definitions are a little easier to understand. m-w.com remains as my default word search, but I find myself cross-checking words at thefreedictionary.com more and more often.
Anyone else have a default online dictionary that they prefer? Any reasons as to why?
