The word "walker" traditionally refers to a person who moves on two legs, with the aid of a walking stick or frame. However, there are many different words that can be used to describe a person who walks in different contexts. For example, hiker and trekker both suggest a person walking in the great outdoors, while roamer and wanderer imply a more aimless form of walking. A stroller or promenader suggests a more leisurely pace, while a marcher is walking with a purpose. A strider suggest a long, confident stride, while a pacer may be walking back and forth in a state of agitation. No matter how a person walks, there is likely a perfect word to describe their gait and purpose.
