"Thin" is such an interesting and versatile word.

THINNER 這個字源自 thin (形容詞) = 稀的, 薄的

英語形容詞有比較級 (comparative) 和最高級 (superlative)

Thin (形容詞) = 稀的, 薄的
Thinner (比較級形容詞) = 比較稀的, 比較薄的
Thinnest (最高級形容詞) = 最稀的, 最薄的

描述事物時, 可用比較級形容詞 (comparative adjective) 說明某事物比另一事物更具某種屬性

比較級通常形容詞加詞尾 “+er”, 某些字前面加 “more”
hard – harder, small - smaller
beautiful – more beautiful, interesting – more interesting
thin - thinner
例外的, good – better, bad – worse

thinner 除了是 thin 的比較級形容詞, 還有一解釋, 做名詞

Thinner (不可數名詞 uncountable noun) = 使變稀薄者；稀釋劑
天拿水是英文 " thinner" 的音譯
- 是無色透明易挥發的液體，微溶于水，能溶于各種有機溶劑，易燃，主要用作喷漆的溶劑

paint thinner (油漆稀釋劑/液)
- a liquid such as turpentine (松節油) that you add to paint to make it less thick
〔松節油等添加到油漆中的〕稀釋液

購買一罐油漆, 顏料, 是濃, 是厚, 是黏滯的, 黏性的 (very viscous)
通常使用天拿水 (Thinner), 添加到油漆中, 溝混一起, 使液體變稀薄, 溝稀些, 容易方便油漆

THIN是稀薄，你去剪髮話偷薄，都係THINNER。
