來自中世紀拉丁語senit,來自阿拉伯語samt,路，通道，詞源同azimuth,縮寫自samt ar-ras,位于頭頂的道路，ras,頭。而該詞最終又來自早期拉丁語semita,旁路，邊路，se-,分開，mita-,改變，詞源同mutual,由羅馬人占據敘利亞時傳入，后來羅馬人離開，公元7世紀左右阿拉伯人又征服了敘利亞，該詞又傳入阿拉伯，最終又在公元14世紀進入了拉丁語。

zenith

zenith: [14] Arabic samt arrās means literally ‘path over the head’. Samt ‘path, road’ made its way via Old Spanish zenit and Old French cenit into English as zenith, bringing with it the metaphorical application to the ‘point in the sky directly overhead’. The plural of samt, sumūt, is the ultimate source of English azimuth [14].
=> azimuth

zenith (n.)

"point of the heavens directly overhead at any place," late 14c., from Old French cenith (Modern French zénith), from Medieval Latin cenit, senit, bungled scribal transliterations of Arabic samt "road, path," abbreviation of samt ar-ras, literally "the way over the head." Letter -m- misread as -ni-.

The Medieval Latin word could as well be influenced by the rough agreement of the Arabic term with classical Latin semita "sidetrack, side path" (notion of "thing going off to the side"), from se- "apart" + *mi-ta-, suffixed zero-grade form of PIE root *mei- (1) "to change" (see mutable). Figurative sense of "highest point or state" is from c. 1600.
