KK: /ˈblækfɪn/
A type of fish that is related to the bluefin tuna, often found in warm waters and known for its dark coloration.
The fisherman caught a blackfin while out at sea.
The word 'blackfin' is formed from 'black' (from Old English 'blæc', meaning dark or without light) and 'fin' (from Old English 'finn', meaning a fin or wing of a fish). The term 'blackfin' refers to a type of fish characterized by its dark-colored fins.
Think of 'black' meaning dark and 'fin' referring to a fish's fin — that's why 'blackfin' describes a fish with dark fins.
