shelter; lean-to (radical only); building (modern simplified for 廣)
广 depicts a roof leaning against a wall, an open-fronted shelter. As radical it wraps the upper-left corner and marks 廊 as a built structure - joining 庙库店庭, all spaces under a roof.
郎 supplies the sound láng directly. The same phonetic appears in 浪狼朗. A faint flavor of stately, gentlemanly bearing matches the elegant covered walkways of classical Chinese architecture - corridors fit for promenading.
