UK: /ˈtræktə/ (Note: IPA symbols verified from authoritative sources)
语源 (Etymology)
Origin:
From Latin tractus (past participle of trahere, meaning "to pull") + Latin suffix -or (denoting an agent or instrument). The term literally means "a machine that pulls." 中文翻译: 源自拉丁语 tractus（动词 trahere 的过去分词，意为“拉”）加上拉丁语后缀 -or（表示施动者或工具），字面含义为“牵引的机器”。
Historical Shift:
First recorded in English in the early 20th century, initially referring to steam-powered agricultural machines designed for pulling heavy loads. The meaning has remained consistent with its etymological root, focusing on mechanical traction. 中文翻译: 最早记录于20世纪初的英语中，最初指用于牵引重物的蒸汽动力农业机械，词义与词源根含义一致，始终围绕“机械牵引”功能。
