Etymology
the word 'sailfish' is a transparent compound formed from two old english roots: 'segl' (sail) and 'fisc' (fish). it is a descriptive name coined in modern english to directly identify the creature by its most distinctive physical feature—the large, sail-like dorsal fin. the logic is purely visual and comparative, with no abstract semantic shift; the ancient meanings of the components are preserved literally in the modern term. this type of compound is common in english for naming species based on prominent characteristics.
