Picture things being carried in and set down in one place. That is the movement the word keeps in all its modern uses. When what is carried in are opinions, several people put theirs on the same table and work out what to do: they confer. When what is carried in is an honour, a degree, or a right, it is carried over and set down on one person, who now has it. The word is formal in every use, and it always involves more than one side.
From the word’s history
Wiktionary traces the word through French to Latin conferō. The modern senses all sit on that Latin verb's idea of bringing things together.
Wiktionary 記的來源是拉丁文 cōnferō，經過法文進入英文。現在的幾個用法，都還貼在那個拉丁動詞「把東西帶到一起」的想法上。
