“reigning world champion”是一個體育領域常用術語，由三個核心詞彙構成：
reigning（形容詞）
指“現任的”或“當前持有頭銜的”，源自動詞“reign”（統治、支配）。牛津英語詞典将其定義為“currently holding a specified title or position”（目前持有特定頭銜或職位）。例如在體育賽事中，該詞特指尚未被擊敗的現任冠軍。
world（名詞作定語）
此處表示“全球範圍内的”，強調競賽的頂級性和國際認可度。根據國際奧委會定義，世界級賽事需滿足至少75個國家/地區參與的标準。
champion（名詞）
指“在競賽中獲勝的個體或團隊”。劍橋詞典将其擴展解釋為“在特定領域表現出卓越能力的主體”。
組合含義：指在所屬領域全球最高級别賽事中獲勝，并持續保持冠軍頭銜至下一屆賽事的個人或團體。例如國際足聯（FIFA）世界杯的現任冠軍隊伍，在衛冕成功前均被稱為“reigning world champion”。該頭銜具有時效性，僅在新一屆賽事産生冠軍後轉移。

二、整體含義
“reigning world champion”指當前仍保持世界冠軍頭銜的個人或團隊，即“衛冕世界冠軍”。例如：
