specified by a preposition (i.e. the Relator is the object of a preposition) that modifies another element within the word group. For example, in the word group τὸ κατʼ ἐμὲ πρόθυμον, the term ἐμὲ is in a relator relationship with the head term πρόθυμον. This relationship only applies to prepositional phrases within word groups and not when the prepositional phrase functions as a clause component.
