## Sunan da asalin
The Modern English term *salmon* is derived from Middle English: samoun,  and , which in turn are from Anglo-Norman: *saumon*, from Old French: saumon, and from Latin: salmō (which in turn might have originated from *salire*, meaning "to leap".). The unpronounced "l" absent from Middle English was later added as a Latinisation to make the word closer to its Latin root. The term *salmon* has mostly displaced its now dialectal synonym *lax*, in turn from Middle English: lax, from Old English: leax, from Proto-Germanic: *lahsaz from Proto-Indo-European: **lakso-*.
