This sense focuses on talk or writing that goes on at length without useful content — it primarily wastes the listener's or reader's time. ⚠️ Distinguish from noun/1 (EMPTY CLAIMS): noun/1 describes content that first sounds impressive but turns out hollow; idiom/2 involves no pretense of impressiveness — it simply lacks substance. Also distinguish from idiom/1 (EMPTY PROMISES), which involves a specific commitment that is never kept, not just unproductive discussion.
