Latin dīrigere, to direct; see direct + -ible.(American Heritage® Dictionary of the English Language, Fourth Edition)
The term arose from attempts in the late 1800s to make a balloon steerable. In French, dirigeable means steerable. Over time the phrase “dirigible balloon” was shortened to just dirigible. In modern parlance, the term has been replaced by airship. (Wiktionary)
