會燒起來的那個溫度
這是字面的一層:point 是刻度上的一個數字,flash 是它到了就會發生的事。
noun · C1
The lowest temperature at which a liquid such as oil gives off enough gas for that gas to catch fire when a flame is brought near it.
閃火點;閃燃點
A good way to hold this word is to take its two parts apart. Flash is something catching light all at once, and point is the exact spot on a scale. Put together, one picture covers the whole entry: the point at which a thing that has been warming quietly finally lights. In a laboratory that point is a temperature, written on the side of a can of oil. Moved onto human life, the same picture describes a place that has been tense for years and needs only a spark, and it describes the second in an evening when the shouting finally starts. In every use, nothing is burning yet a moment before, and everything is a moment after.
Wiktionary gives the make-up of the word plainly: flashpoint is from flash plus point. The packet says nothing about which use came first, so no order is claimed here.
Wiktionary 只記了這個字的組成:flashpoint 由 flash 加 point 而來。證據沒有說哪個用法先出現,所以這裡不做先後的推論。
