翹翹板 與 鋸子, see and saw

saw 作動詞是鉅東西 , 也是 see 的過去式
saw 作名詞則是鋸子

傳說中的句子 : 鋸(n)鋸(v)鋸(n)
i saw a saw saw a saw

seesaw 合在一起就成了翹翹板
是否因翹翹板 高低來回擺動 看來就像鋸齒往復呢?

sightsee (v) : to visit famous sights (景點旅遊)
sightsaw 則是 sightsee 的過去式

[example]
The aged man sightsaw on his own by Taiwan Taveling Bus
and played on a seesaw in the green park without balance ...

//===
seesaw == fulcrum(支點) + lever(槓桿)
兩端的承載通常稱為 load 與 effort

seesaw其實就像大的天平, Libra (Balance, Scales)

Libra 天平(天秤)座, 12星座中的第七個
libra 也是重量的單位
1 libra = 1 lb = 1 pound = 1鎊 = 12盎司(ounces)
[古羅馬重量單位?]

Libra  讓我聯想到
天平上的瑪爾濟斯
秤桿子挑江山 - 劉羅鍋

司法允善 如秤 平人心
司法允惡 如鋸 斷朝綱
...

沒有Libra 則成Cobra
沒有Equilibrium 則需 Librium

No Libra, then Cobra
No Equilibrium, then Librium
