What is another word for air-raid shelter?
Pronunciation: [ˈe͡əɹˈe͡ɪd ʃˈɛltə] (IPA) 
Air-raid shelters are underground structures designed to protect people during bombing or air-raid attacks. However, the term "air-raid shelter" is not the only term used to describe such structures. Alternative synonyms for the word include bomb shelter, underground bunker, fallout shelter, blast shelter, and safe room. Bomb shelters are commonly built to protect against explosive attacks, especially during times of war. Fallout shelters, on the other hand, are designed to protect the occupants from the radioactive fallout that may result from a nuclear explosion. While all these terms are synonyms for "air-raid shelter," they reflect the different purposes for which such structures are built.
