by the way

Etymology
First appeared in the 10th century with literal meaning "by the side of the road", from Old English (which became "") meaning "road". Soon afterward (circa 1000) it came to mean "during one's journey". The figurative meaning developed in the mid-16th century, with the first instance of the modern meaning being from 1614.
