Wiktionary (/wɪkʃənəri/) is a wiki-based dictionary, a sister project to Wikipedia, run by the Wikimedia Foundation.
It is available in English and other languages, but each version also accepts both L1 and foreign entries.
The English entry has about 6 million content pages as of 2019, which is more than the English Wikipedia. Note that this is total different spellings in all their forms, rather than headwords.
Unfortunately, Wiki software isn't well-designed to deal with either multiple languages or homographs. The entry on "love" for example contains a main entry for English, plus additional entries for Czech, Danish, Dutch, French, Friulian, Inari Sami, Middle Dutch, Middle English, Norwegian Bokmål, Norwegian Nynorsk, Romani and Serbo-Croatian(!)
Meanwhile, the entry for "like" has no less than 9 entries in English, covering its use as a noun, 2 different verbs, an adjective, an adverb, a conjunction, and a preposition or particle(!)
Separate pages for each headword do not exist.
Technically speaking, Wiktionary classifies words according to traditional grammar rather than modern scientific grammar.
They also fail to identify (1) which verbs can undergo dative shift and those which can't and (2) reporting verbs.
