身體或東西真的站直
這一組就是字面本身：方向朝上、沒有倒下去。柱子、莖、耳朵是東西站直；法庭上的一句喊話是人站直。

Standing straight up, or pointing upwards. It is used about things such as posts, stems, hairs, or ears, and about a person who is on their feet.
直立的
核心畫面
You can think of upstanding as one posture: something has come up onto its feet and is holding there. A post set straight in the ground. A whole room rising as an important person walks in. English then lends that same posture to a person's character, so that someone who stands straight is someone who does not bend when bending would be easier.
「upstanding」可以想成一個姿勢：立起來，而且維持著。一根柱子直直插在地上，不歪也不倒。一屋子的人在重要人物…更多收起
「upstanding」可以想成一個姿勢：立起來，而且維持著。一根柱子直直插在地上，不歪也不倒。一屋子的人在重要人物進門時整齊站起來。英文把這個姿勢借去講人：站得直的人，就是那種在「彎一下比較輕鬆」的時候還是不彎的人。中文說「立身正直」「站得正」，用的其實是同一個畫面。From the word’s history
The packet's Wiktionary extract records two entries: the honest adjective is from up- + standing, and the standing-up adjective is from the verb upstand. Both are built from the same two pieces, so the picture of standing straight sits under each of them.
來源的 Wiktionary 抄錄分成兩個詞源條目：「正直」這個形容詞來自 up- 加 standing，「站立」這個形容詞來自動詞 upstand。兩邊用的零件一樣，所以「站直」這個畫面在兩個意思底下都成立。這是詞源的紀錄，不是我們替它編出來的故事。

人品站得正
把「站得直」從身體搬到為人處世上。一個 upstanding 的人，是別人信得過、扛得起責任的人。詞源上 Wiktionary 把它另列一條（up- + standing），所以這個連結是一個好用的畫面，不必當成歷史上的直接衍生。
