To carry or drag something heavy or awkward with great effort.
n
A projecting piece on an object, used for carrying, lifting, or attaching it.
Etymology
The word 'lug' likely entered Middle English from Scandinavian languages, akin to the Swedish 'lugga' meaning to pull by the hair. Its ultimate origin is obscure but may be imitative in nature, possibly echoing the sound or sensation of something being dragged heavily or with resistance. This core sense of laborious pulling or carrying evolved to also describe a handle or projection, as it is the part by which an object is lugged. Thus, the word connects the physical action to the physical feature designed for that action.
Analysis
This is a simplex word of likely Scandinavian origin. The form 'lug-' functions as the core root, carrying the sense of pulling or dragging.
