escort

1. The notion underlying escort is of 'guidance', of 'showing the right path'.
2. ex- => es- + (correct => corrig- => corg- => cort-) => escort.
3. 词源上这个词和correct同源，但引申较多，在此用联想。es前缀“外边”，cort看成cart（二轮运货马车），字面义“在马车外”。古时护镖人跟随马车一路前行，又有关云长千里走单骑护送兄妻，也是一路走在马车外边。

escort 护送

来自拉丁文*excorrigere, 引导，护送，来自词根rig, 竖立，坚直，词源同right, erect. 原为军事术语。

escort

escort: [16] The notion underlying escort is of ‘guidance’, of ‘showing the right path’. The word comes via French from Italian scorta ‘guide’, a noun use of the past participle of scorgere ‘show, guide’. This in turn came from Vulgar Latin *excorrigere, a compound verb formed from the prefix ex- ‘out’ and Latin corrigere ‘put right’ (source of English correct).
=> correct
