The Merriam-Webster Visual Dictionary is a great online tool for finding the correct terminology (in six languages!) for a wide variety of objects. Search by word or by theme; find an illustration and the words for its constituent parts. The dictionary currently consists of 20,000 terms with contextual definitions and 6,000 full-color images!
