I'd never heard this word so I looked it up. Google didn't have a definition but merriam-webster was the first result. They showed me an extra concise definition and then this message...
>Wait, there’s more! This word doesn't usually appear in our free dictionary, but we’ve shared just a bit of the information that appears in our premium Unabridged Dictionary. There’s more definition detail there. Start your FREE Trial Now!
Umm.. Fuck you Merriam-Webster?
In other words, there used to be such a thing as 'too much dictionary'. Now, like any other information source, it's the size of my phone, except when it's the size of my laptop.
When I was taking a formal class in Mandarin, some classmates complained, "the definitions you're getting from Pleco are so much better than ours! What are you doing differently?" They lost interest when I responded "I paid for the better dictionaries".
Different dictionaries have different strengths. CC-CEDICT has entries for standard Chinese versions of western names, and for slang. Then again, it doesn't even have usage examples. ABC has many, many entries, including stuff like technical terms in linguistics. Tuttle Learners' has very few entries (it's a learners' dictionary!), but it does nice things like provide antonyms and, where it might be helpful, character-by-character glosses. Tuttle has my favorite entry for 糟糕 [a mess/very bad/bad luck], headed by "[modif: 糟 messy + 糕 cake]".
If you know the word "duplicate", though, you should be able to figure this one out.
