Meander comes from Greek Maiandros, an old name for a winding river in Asia Minor that is now known as the Menderes. To the Latin maeander, to the English Manderes, and finally to Meander in the early 16th century as a noun,  Despite this origin, the word is more commonly used to refer to a person's wandering course than a river's. 

The word "meandering" was first used in English in the early 1600s. The earliest known use of the adjective "meandering" was in 1617 by William Drummond, a poet and pamphleteer.
