The phrase functions as a question, seeking to identify the sibling of Scott Pryor. Grammatically, “who” acts as the interrogative pronoun, “is” as the linking verb, “Scott Pryor” as the proper noun subject’s possessive modifier, and “sister” as the noun complement. This construction is a common way to inquire about familial relationships.
Understanding this question’s structure is crucial for effective online searches. Search engines interpret queries based on their grammatical components. Recognizing the parts of speech helps predict how search algorithms will process the query and retrieve relevant results. This knowledge aids in crafting precise searches, especially when seeking information about individuals with common names. Genealogical research, journalistic investigations, or simply satisfying curiosity about public figures often benefit from this level of precision.
