What is the difference between 火 and 灭?

火 means 'fire', while 灭 means 'to extinguish' or 'to go out'.

火 is a noun for fire. 灭 is a verb meaning to put out a fire or for a fire to die out. They look somewhat similar because 灭 has a 火 component on the bottom, but the meaning is opposite: 火 is the fire itself, 灭 is the action of stopping it.

Why does 火车 (train) contain the character for fire?

火车 literally means 'fire vehicle' because early trains were powered by steam from burning coal.

In the past, trains used steam engines that burned coal or wood to heat water and create steam. So the name 火车 (fire vehicle) stuck, even though modern trains may not use fire. This is a common example of how Chinese words can preserve old technology in their names.

DimensionNaturalAvoid
Literal meaning火车 = fire vehicleNot 'fire train' in English
Modern meaningTrain (any type)Not necessarily steam-powered
Memory hookThink of old steam trains with fireDon't assume 火 means actual fire today
