| Remarks | 'Jack' from Middle English 'Jacke', i.e., nickname for Johan/John and generally applies to men (p. 644 in Ref. 11978); 'salmon' replaced Old English 'laex' (German 'lachs'; Swedish 'lax', source of English 'gravlax'; Yiddish 'laks', source of English 'lox', i.e., smoked salmon; Russian 'losos') borrowed from Anglo-Norman 'saumoun' from Latin 'salmo, -onis' linked to 'salire', i.e., to jump and hence, the leaping fish (p. 454 in Ref. 11979). |
