dolphin-safe

The term is a modern compound adjective, a product of 20th-century environmental activism. The first element, "dolphin," traces back to the Greek delphis, a name for the marine mammal. The second element, "safe," originates from Latin salvus, carrying the core meaning of being unharmed. The compound was coined to label tuna caught with fishing techniques, such as using purse seines without encircling dolphins, that are specifically designed to ensure the safety of dolphin populations often found swimming near tuna schools. It represents a direct application of the literal meanings of its components to create a precise, legally-defined marketing and ecological standard.
