IPA: /ˈkwɪl.bæk/
KK: /ˈkwɪlˌbæk/
A type of freshwater fish found in North America, known for its long dorsal fin ray that stands out from the others.
The fisherman caught a quillback while fishing in the river.
Quillback is formed from "quill" (from Middle English *quil*, meaning a feather or spine) and "back" (from Old English *bæce*, meaning the rear part of something). The word refers to a type of fish known for its spiny fins, resembling quills on its back.
Think of 'quill' as a feather or spine, and 'back' as the rear part — together they describe a fish with spiny features on its back.
