词根词缀：-bust, -ust, -bur; bust-, bur-, ur-

【来源及含义】Latin: burere, "to burn up"; from urere, with an inserted or faulty separation of b in amburere, "to burn around"; which stands for amb-urere, "to burn around", but it was misdivided into am-burere and because of this misdivision, the new verb burere was formed with the past participle bustum; so, it really came from urere, "to burn, to singe"

词根词缀：inter-, intero-

【来源及含义】Latin: between; among, mutually, together; on the inside, internal

【相关描述】Although abstracted from the many compounds in which it entered English, the form inter- was not generally considered a living prefix in English until the 1400s.

During the later period of Middle English many words borrowed in the Old and Middle French forms entre-, enter- began to be consciously respelled with Latin inter-; although vestiges of the older French borrowings are found in entertain and enterprise.

The living prefix inter- is now freely added to almost any element in English to create such formations with the meaning of "between" and "among". The words formed by intra- are closely related to this inter- prefix; in fact, they both apparently came from the same Latin source.

词根词缀：serv- (slave)

【来源及含义】Latin: servire, to serve, to be a slave; slave; slavery

【相关描述】From Latin servire, to be a slave, to serve; from servus, slave, which is an Etruscan loan word. Of course, the modern use of "serve" has gone beyond the "slavery" aspect, but we are considering the etymology of the words which apparently came from the original idea of "slavery".

This Latin serv- is not related to another serv-, -serve which means "to save, to preserve".

词根词缀：zelo-, zel-; zeal-

【来源及含义】Greek > Latin: ardor, fervor; jealousy, jealous

【相关描述】Etymologically, jealousy and zeal came from the same source. Both originally came from Greek zelos. This passed into post-classical Latin as zelus, which later produced the adjective zelosus. Old French incorporated this as gelos or jelous and passed it on to English.

The Greek word denoted "jealousy" and "fervor, enthusiasm", and it is this strand of meaning that has come down to us as jealous. Jalousie was the French equivalent of jealousy. Most of the words that became distinctive terms for "jealousy" were originally used in a good sense of "zeal" and "emulation".
