About Wiktionary
Wiktionary is a collaborative dictionary covering hundreds of languages, including definitions, etymologies and pronunciations. It is far less known than Wikipedia but is one of the largest freely licensed lexical resources that exists. Because it is built by volunteers rather than lexicographers, its coverage is uneven: some minority languages are documented in more depth than any commercial dictionary offers.
