assess [assess 词源字典]: assess: [15] The literal meaning of Latin assidēre, ultimate source of assess, was ‘sit beside someone’ (it was a compound verb formed from the prefix ad- ‘near’ and sedēre ‘sit’, a relative of English sit). This developed the secondary meaning ‘sit next to a judge and assist him in his deliberations’ (which lies behind English assize), and in medieval Latin the sense passed from helping the judge to performing his functions, particularly in fixing the amount of a fine or tax to be paid.

Hence English assess, which came via Old French assesser from Latin assess-, the past participial stem of assidēre. (The Latin adjective assiduus, formed from assidēre in the sense ‘apply oneself to something’, gave English assiduous [16].)
=> assiduous, assize, session, sit, size[assess etymology, assess origin, 英语词源]
succeed: succeed: [15] To succeed someone is etymologically to ‘go next to them’, hence to follow them. The word comes via Old French succeder from Latin succēdere, a compound verb formed from the prefix sub- ‘under’ (used here in the sense ‘next below’, hence ‘next to, after’) and cēdere ‘go’ (source also of English cede, exceed, proceed, etc). The notion of ‘getting near to something’ evolved in Latin into ‘doing well, prospering’ – whence the other main meaning of English succeed.
=> cede, excede, proceed, success

weasel (v.): "to deprive (a word or phrase) of its meaning," 1900, from weasel (n.); so used because the weasel sucks out the contents of eggs, leaving the shell intact. Both this and weasel-word are first attested in "The Stained-Glass Political Platform," a short story by Stewart Chaplin, first printed in "Century Magazine," June 1900:
"Why, weasel words are words that suck all the life out of the words next to them, just as a weasel sucks an egg and leaves the shell. If you heft the egg afterward it's as light as a feather, and not very filling when you're hungry; but a basketful of them would make quite a show, and would bamboozle the unwary."
They were picked up at once in American political slang. The sense of "extricate oneself (from a difficult place) like a weasel" is first recorded 1925; that of "to evade and equivocate" is from 1956. Related: Weasled; weasling.
