A journey or voyage undertaken by a group of people with a particular purpose, especially that of exploration, scientific research, or war.

Implies a highly organized, purposeful, and often dangerous journey, rather than a casual vacation or simple trip.

The story behind the word. Derived from the Latin 'expeditio', which comes from 'expedire', meaning 'to extricate, prepare, or set free.' Literally, it translates to 'to free the feet' (from 'ex-' meaning out + 'pes/pedis' meaning foot). It originally referred to preparing a military force for prompt action by freeing them from obstacles.
