Final answer:
A crocket is the projecting ornament often shaped like curved foliage, used in Gothic architecture to decorate pinnacles, spires, and gables.
Step-by-step explanation:
The projecting ornament typically found at the outer angles of pinnacles, spires, and gables in Gothic architecture is known as a crocket. Crockets are carved in the form of curved foliage and are a hallmark of the Gothic style's emphasis on verticality and intricate detail. These ornaments are part of the rich gothic ornamentation which includes other elements like the lancet windows, ribbed groin vaults, kings gallery, and the use of tracery in rose windows. The pointed arch is a fundamental element in Gothic architecture that allows for more efficient distribution of weight and enables the ornate stonework seen in elements like tracery and the decorative carving on columns and piers.
