ngã lộn nhào, bị đổ
"Fall over" is a combination of two simple, ancient words: * **Fall:** This word originates from Old English "feallan," meaning "to fall," ultimately stemming from Proto-Germanic *fallaną. * **Over:** This word is derived from Old English "ofer," meaning "above, beyond, over." The combination of these words to form "fall over" signifies the action of losing balance and moving from an upright position to a horizontal one, often with a sudden and uncontrolled motion. This simple phrase encapsulates a common human experience and has been used in English for centuries.
