Eloquent Arabic may leave an element unstated when context supplies it. This is ḥadhf (ellipsis), and the understood element is called taqdīr. Such supplementation cannot be arbitrary; grammar and context must support it.
“Ask the town” (Yūsuf 12:82) means to ask the people of the town, not the buildings. An implied reference to the inhabitants explains how the expression works without rewriting the verse.
The interpreter preserves the revealed wording while identifying the contextual element needed to understand it.
