Final answer:
The term 'Meander' meaning to wander in an aimless, circuitous way comes from the Meander River in Turkey known for its winding course.
Step-by-step explanation:
The word that means to wander in an aimless, circuitous way, which also refers to the course of a river in present-day Turkey, is Meander. This term originates from the behaviors observed in rivers, where the river erodes sediment from the outer bend and deposits it on the inner bend, creating a sinuous path as it travels. The Meander River, also known as the Maeander or Büyük Menderes River in present-day Turkey, is famously winding and has thus given its name to the term meandering, describing such indirect or aimless paths, which can also be applied to describe the behavior of people or objects.
