長桿(實物與動作)
核心那根桿子本身,以及拿它來使力的動作。
pole (stick) · noun · C2
A long thin stick made of wood or metal, often stood up straight in the ground to hold something up.
桿子
You can hold the everyday pole as a long, thin, straight stick of wood or metal, often stood upright in the ground to hold something up — a , a tent pole. Note that pole hides two different words that ended up spelled alike: this stick-pole, and a separate 'end of an axis' pole.
The stick sense comes from Latin palus 'stake', via Old English pal — a driven-in post. That gives the upright, load-bearing stick still at the core.
「桿子」這一支來自拉丁文 palus(樁、椿),經古英語 pal 進來——就是打進地裡的一根柱子,所以核心一直是那根立起來、能撐住東西的桿。

pole (stick) · noun · C2
A long thin stick made of wood or metal, often stood up straight in the ground to hold something up.
桿子
軸的端點(地極、磁極、電極)
這一支跟桿子無關,是另一個來源:東西繞著一根軸轉,軸的兩個端點就叫 pole。地球、磁鐵、電池都有這樣一頭一尾的兩端。
pole (of the earth) · noun · C2
The point at the very top or very bottom of the Earth or another planet.
極(地極)
相隔最遠的兩極(比喻)
從「軸的兩端」再走一步:南北兩極是地球上相隔最遠的兩點,於是 pole 拿來比喻兩個對立到不能再對立的立場。
opposite extreme · noun · C2
One of two ideas, opinions, or situations that are the complete opposite of each other.
兩極、對立面
