The Latin root word *rog* means "ask." This Latin root is the word origin of a fair number of English vocabulary words, including inter[*rog*]ate, ar[*rog*]ant, and pre[*rog*]ative. The root *rog* is easily recalled via the word inter[*rog*]ative, for an inter[*rog*]ative is a question word that "asks" a question, such as "who," "what," "how," "why," or "where."
