It comes from the French word 'terne,' meaning dull, tarnished, or lacking luster, which describes the matte grey appearance of the lead-tin coating.
Historic terne metal contained lead. Modern terne-coated stainless steel uses a safe, lead-free or very low-lead alloy, but handling historic terne requires precautions for lead exposure.
Both are steel sheets coated with a tin alloy. Tinplate has a bright, shiny coating of nearly pure tin. Terne metal has a 'dull' (terne) coating that is predominantly lead with some tin, giving it a grey colour and different material properties.
