As a writer, I rarely need to look up the definition of a word. If I don't know a word, I'm not going to risk using it. However, I frequently check that a word has the exact nuance I want. If it does not, I turn to a thesaurus to search for a closer alternative. Unfortunately, a regular dictionary is next to useless for these purposes. That is why I was pleased to discover dict [1], which not only has the information needed for such purposes, but runs from the command line for added efficiency.

A client for the DICT [2] dictionary network protocol, dict essentially searches several dozen databases and returns comprehensive results in seconds. It is available for major distributions, but note that each database is often in a separate package in distro repositories and must be installed separately from the basic command. The option --dbs (-D) will show a list of these databases, as will the web version [3] of dict (Figure 1).

Another option is to specify a specific database so that only the relevant results are given, using the option --database (-d) DATABASE. For instance
