Complete jinās includes the similar-category type and the differing-category type.
Similar-category: The paired expressions are of the same grammatical kind, such as two nouns, but denote different things. The two uses of “hour” exemplify the underlying idea.
Differing-category: The outward form agrees even though one occurrence may function as a noun and the other as a verb. Formal resemblance does not require identical grammatical roles.
Method: Verify the four formal conditions first, then examine the contextual meaning and grammatical class of each occurrence.
