IPA: /ˈsiːbɜːrd/
KK: /ˈsiːbɜːrd/
A type of bird that lives mainly near the sea and often flies over the ocean.
The seabird soared gracefully above the waves, searching for fish.
Seabird is formed from "sea" (from Old English "sǣ", meaning the large body of saltwater) and "bird" (from Old English "brid", meaning a flying animal). The word refers to a bird that lives or is found in the sea or ocean environment.
Think of a bird that lives in the 'sea' — that's why 'seabird' means a bird associated with the ocean.
