the.com/seine

means A large fishing net that hangs vertically in the water, weighted at the bottom and floated at the top, used to encircle and trap fish — also the verb for fishing with one.

from The word 'seine' (the net) traces back through Old English 'segne' and Latin 'sagena' to Greek 'sagēnē,' meaning a large fishing net or drag-net — nothing to do with the Paris river at all. The river Seine gets its name separately, from the Gaulish 'Sequana,' the river's own ancient goddess-name, later Latinized. Two words, same spelling by sheer coincidence — one hauls fish, the other hauls Parisians past cafés.
