Pattern: if-subject-verb
Structure Overview
Formula: Verb (ask, wonder, know) + if + Subject + Verb
Core Meaning: This pattern uses "if" not as a conditional trigger, but as a nominalizer (similar to "whether"). It embeds a yes/no question into a declarative sentence to express uncertainty, report speech, or make a request more polite.
