IPA: /ˈseɪnər/
KK: /ˈseɪnər/
A person or boat that catches fish using a special net called a seine.
The seiner returned with a large catch of fish after a long day at sea.
The word 'seiner' comes from the Old French 'seine' (meaning a fishing net) combined with the suffix '-er' (meaning a person who). A 'seiner' is therefore a person who uses a seine for fishing.
Think of a person who uses a 'net' ('seine') for fishing — that's what a 'seiner' does.
