emerge [emerge 词源字典]: emerge: see merge
[emerge etymology, emerge origin, 英语词源]
merge: merge: [17] Merge comes from Latin mergere, which meant ‘dive, plunge’ (it was also the source of English emerge [16], which etymologically means ‘rise out of a liquid’, immerse [17], and submerge [17]). Merge was originally used for ‘immerse’ in English too, and the modern meaning ‘combine into one’ did not emerge fully until as recently as the 20th century. It arose from the notion of one thing ‘sinking’ into another and losing its identity; in the 1920s this was applied to two business companies amalgamating, and the general sense ‘combine’ followed from it.
