Conjecture

🎴

Jut (mid 16th century) is a variant of jet in this sense. Jacere is found in a large number of English words including abject (Late Middle English) literally ‘thrown away’; conjecture (Late Middle English) ‘throw together’; deject (Late Middle English) ‘thrown down’; ejaculate (late 16th century) from jaculum ‘dart, something thrown’; eject (Late Middle English) ‘throw out’; inject (late 16th century) ‘throw in’; jetty (Late Middle English) something thrown out into the water; project (Late Middle English) ‘throw forth’; subject (Middle English) ‘thrown under’; trajectory (late 17th century) ‘something thrown across’.

1. 英语中的 "conjecture" 来自于拉丁动词 "conicere"，它由前缀 "con-" 和 "iacere" 组成。
2. "con-" 是一个加强意味的前缀，在拉丁语中意味着"together"或"with"。
3. "iacere" 在拉丁语中意味着"to throw"。

因此，字面上，“conicere”意味着“投掷在一起”或“抛向一起”。在过去的语境中，它是指把片段或迹象放在一起，从而得出或“推测”某个结论。随着时间的推移，“conjecture”这个词在英语中逐渐获得了“猜测”或“假设”的含义，这通常基于有限的证据或没有确定的证据。
