Etymology
The term 'salmonid' is a modern scientific construct, directly formed in the 19th century for precise biological classification. It combines the common name 'salmon', which itself has a long history through Old French and Latin, with the specialized taxonomic suffix '-id'. This suffix, borrowed from New Latin '-idae', traces back to the Greek patronymic ending '-idēs', used to denote 'offspring of' or 'descendant of'. Thus, the word's literal construction means 'of the salmon family', logically designating all fish species classified within the same biological family as the salmon.
Analysis
'salmon' is derived from Latin 'salmo, salmon-', meaning 'salmon'. The suffix '-id' is from New Latin '-idae', a plural suffix used in taxonomic names for animal families, ultimately from Greek '-idēs', meaning 'belonging to' or 'descended from'.
