The adjective pragmatic means doing something in a practical way, rather than theoretical.

Synonyms are practical, down-to-earth, realistic or efficient.

The word origins 1610, from meddlesome, impertinently busy and middle French pragmatique (1500). From Latin pragmaticus meaning skilled in business or law or Greek pragmatikos (fit for business, active, business-like, systematic). The word has been used since the late 19th century in reference to philosophical movement pragmatism. Most often the word today is used to describe people (or ourselves).
