- conjecture
[conjecture 词源字典] - conjecture: [14] A conjecture is, etymologically speaking, simply something ‘thrown together’. The word comes, perhaps via Old French, from Latin conjectūra ‘conclusion, interpretation’, a noun derived from the past participle of conicere ‘throw together’. This was a compound verb formed from the prefix com- ‘together’ and jacere ‘throw’ (source of English jet, jettison, and jetty). The notion behind the word’s semantic development is that facts are ‘thrown together’ in the mind and (provisional) conclusions drawn.
