The military parade was grand and imposing — unforgettable.
Tips
usage
Strong, positive, and a touch grand. Common subjects: rivers, mountains, music, military parades, historical writing, calligraphy. For small-scale grandeur use 气势不凡 instead.
memory
磅礴 is a rhyming binome meaning 'vast, sweeping' — the two characters reinforce each other for aural effect. Literally 'momentum's force — vast and sweeping.'
