"A lexical database for the English language".

That is, a dictionary.

There is an online version [http://wordnet.princeton.edu/cgi-bin/webwn] and an off-line version [http://wordnet.princeton.edu/wn2.0.shtml]. The off-line version is avalable for [Windows] and [Unix].

It is mentioned here because it is based on Tcl/Tk.
