联想：posse 开头像“pos”（position 位置），一群人各就各位聚成一伙。注意发音是 /ˈpɒsi/，别读成 possess。
语域：neutral 常见场景：日常交谈（朋友或同伴群体）、新闻报道（一群记者或围观者）、历史/法律（治安官召集的民团） 该词在表示‘一群人’时，通常语气比较轻松，多用于日常口语或新闻报道中；在历史或法律语境中则指由治安官召集的民团。整体正式程度接近中性，正式写作中也可使用。
与 posse 押韵：bossy /ˈbɒsi/、glossy /ˈɡlɒsi/（重读元音为 /ɒ/，后面是 /si/）。形似但不押韵：possible /ˈpɒsəbl/ 和 possum /ˈpɒsəm/ 以 /pɒs/ 开头，但词尾不是 /si/；positive 中的 s 读 /z/（/ˈpɒz-/）；pose 读 /pəʊz/，元音和尾音都不同。
