This is the most recent version of the concept list underlying the [Intercontinental Dictionary Series](https://ids.clld.org/) which was first launched in 2007 and now significantly enhanced and expanded (while the concept list itself was left unchanged). The list also served as the core list underlying the [World Loanwoard Database](http://wold.clld.org) and was used for the investigation of cross-linguistic colexification patterns in the [CLICS database](http://clics.lingpy.org).
