Languages with the Most Words in the Dictionary

Although it is possible to count the number of entries in a dictionary, it is not possible to count the number of words in a language. In compiling a dictionary, a lexicographer decides whether the evidence of use is sufficient to justify an entry in the dictionary. This decision is not the same as determining whether the word exists. Name the languages that have the most words in their most complete authoritative dictionaries. The number of native speakers is given as a hint, and the name of the dictionary will appear after you guess each language (two hard ones are given as automatic hints).
