IPA: /əˈbleɪtə/
KK: /əˈbleɪtər/
A material or surface that wears away or is removed when exposed to heat, often used in spacecraft or rocket engines to protect against high temperatures.
The spacecraft was equipped with an ablator to protect it from the intense heat during reentry into the Earth's atmosphere.
Ablator is formed from "ab-" (meaning away) and "latere" (meaning to carry or bring). The word refers to something that carries away material, often used in contexts like aerospace engineering where it describes materials that are designed to be removed or eroded during flight.
Think of something that 'carries away' ('latere') material 'away' ('ab-') — that's why an ablator is a material that removes itself during use.
