Something that stays put through all the time ahead — it does not run out, wear off, or change back.
From the word’s history
From Latin permanere = per- (through) + manere (to stay, remain) — to stay through to the end. What is permanent stays through time instead of stopping partway.
來自拉丁文 permanere：per-（穿過）＋ manere（停留、留下），意思是「一路留到最後」。permanent 的東西就是能穿過時間繼續留著，而不是中途就停、就消失。
