amphibious
am-FIB-ee-uhs
/æmˈfɪbiəs/
Relating to or capable of operating both on land and in water.
Often used in military contexts for operations involving forces moving from sea to land, or for vehicles designed for both environments.
The story behind the word. The word 'amphibious' comes from ancient Greek, combining 'amphi-' meaning 'both' or 'on both sides,' and 'bios' meaning 'life.' So, an 'amphibious' creature or operation is one that can exist or function in 'both lives' or 'both environments' – specifically, land and water. It's a perfect descriptor for creatures like frogs and military operations that transition from sea to shore.

Example sentences

- "Frogs are amphibious creatures, spending part of their lives in water and part on land." Referring to an animal.
Memory hook
AMPHI means 'both,' and BI-ous sounds like 'bio' for life. So, 'life in both' (land and water). Both lives (land/water)
When not to use
Do not use 'amphibious' for things that merely float or are waterproof; it implies active capability in both environments.
Fun facts
- The first recorded use of the term 'amphibious' for military operations dates back to the 17th century.
