2、chowder:  Chowder, a North American seafood soup, probably takes its name from the pot in which it was originally cooked – French chaudière ‘stew pot’. This came from late Latin caldāria ‘pot’, a descendant of Latin calidārium ‘hot bath’ (which lies behind English cauldron); this in turn was a derivative of the adjective calidus ‘warm’.=> calorie, cauldron

The word and the practice introduced in Newfoundland by Breton fishermen, and spreading thence to New England. CHOWDER. A favorite dish in New England, made of fish, pork, onions, and biscuit stewed together. Cider and champagne are sometimes added. Pic-nic parties to the sea-shore generally have a dish of chowder, prepared by themselves in some grove near the beach, from fish caught at the same time. [John Russell Bartlett,"Dictionary of Americanisms,"1859] The derogatory chowderhead (1819) is a corruption of cholter-head (16c.), from jolthead, which is of unknown origin.
